Each PF/VF has a limited number of vlan filters for
configuration purposes; This information is passed to qede
and is used to prevent over-usage - once a vlan is to be
configured and no filter credit is available, the driver
would switch into working in vlan-promisc mode.
Problem is the credit pool is shared by both PFs and VFs,
and currently PFs aren't deducting the filters that are
reserved for their VFs from their quota, which may lead
to some vlan filters failing unknowingly due to lack of credit.

One of the goals of the vf's first message to the PF [acquire]
is to learn about the number of resources available to it [macs, vlans,
etc.]. This is done via negotiation - the VF requires a set of resources,
which the PF either approves or disaproves and sends a smaller set of
resources as alternative. In this later case, the VF is then expected to
either abort the probe or re-send the acquire message with less
required resources.
While this infrastructure exists since the initial submision of qed
SRIOV support, it's in fact completely inoperational - PF isn't really
looking into the resources the VF has asked for and is never going to
reply to the VF that it lacks resources.
This patch addresses this flow, fixing it and allowing the PF and VF

major number can co-exist even if their minor is different.

One timer, whose handler keeps reading on MMIO register for EEH
core to detect error in time, is started when the PCI device driver
is loaded. MMIO register can't be accessed during PE reset in EEH
recovery. Otherwise, the unexpected recursive error is triggered.
The timer isn't closed that time if the interface isn't brought
up. So the unexpected recursive error is seen during EEH recovery
when the interface is down.
This avoids the unexpected recursive EEH error by closing the timer
in qlge_io_error_detected() before EEH PE reset unconditionally. The
timer is started unconditionally after EEH PE reset in qlge_io_resume().
Also, the timer should be closed unconditionally when the device is
removed from the system permanently in qlge_io_error_detected().

Driver incorrectly uses dma_unmap_addr_set() to set

[i.e not defined using DEFINE_DMA_UNMAP_ADDR()] and is
being used by the driver flows other than unmapping
physical addresses. This patch fixes driver fastpath

Many developers already know that field for reference count of the
struct page is _count and atomic type. They would try to handle it
directly and this could break the purpose of page reference count
tracepoint. To prevent direct _count modification, this patch rename it
to _refcount and add warning message on the code. After that, developer
who need to handle reference count will find that field should not be
accessed directly.

PF updates its VFs' bulletin boards with link configurations whenever
the physical carrier changes or whenever hyper-user explicitly requires
some setting of the VFs link via the hypervisor's PF.
Since the bulletin board is getting cleaned as part of the IOV disable
flow on the PF side, re-enabling sriov would lead to a VF that sees the
carrier as 'down', until an event causing the PF to re-fill the bulletin
with the link configuration would occur.
To fix this we simply refelect the link state during the flows, giving
the later VFs a default reflecting the PFs link state.

As the VF infrastructure is supposed to offer backward/forward
compatibility, the various types associated with VF<->PF communication
should be aligned across all various platforms that support IOV
on our family of adapters.
This adds a couple of currently missing values, specifically aligning
the enum for the various TLVs possible in the communication between them.
It then adds the PF implementation for some of those missing VF requests.
This support isn't really necessary for the Linux VF as those VFs aren't
requiring it [at least today], but are required by VFs running on other
OSes. LRO is an example of one such configuration.

Up to this point, VF and PF communication always originates from VF.
As a result, VF cannot be notified of any async changes, and specifically
cannot be informed of the current link state.
This introduces the bulletin board, the mechanism through which the PF
is going to communicate async notifications back to the VF. basically,
it's a well-defined structure agreed by both PF and VF which the VF would
continuously poll and into which the PF would DMA messages when needed.
[Bulletin board is actually allocated and communicated in previous patches
but never before used]
Based on the bulletin infrastructure, the VF can query its link status
and receive said async carrier changes.

Communication between VF and PF is based on a dedicated HW channel;
VF will prepare a messge, and by signaling the HW the PF would get a
notification of that message existance. The PF would then copy the
message, process it and DMA an answer back to the VF as a response.
The messages themselves are TLV-based - allowing easier backward/forward
compatibility.
This patch adds the infrastructure of the channel on the PF side -
starting with the arrival of the notification and ending with DMAing
the response back to the VF.
It also adds a dummy-response as reference, as it only lays the
groundwork of the communication; it doesn't really add support of any

qede requires qed to provide enough resources to accommodate 16 combined

Instead, qed inform back to qede how many channels can be opened based on
available resources - but that calculation doesn't really take into account
the resources requested by qede; Instead it considers other FW/HW available
resources.
As a result, if a user would increase the number of channels to more than
16 [e.g., using ethtool] the chip would hang.
This change increments the resources requested by qede to 64 combined

that section should include the setting of the shared memory as well as
the sending of the command [otherwise a race might send a command with
the data of a different command].
2. It moves the locking scheme from using mutices into using spinlocks.
This lays the groundwork for sending MFW commands from non-sleepable
contexts.

When device is configured for Multi-function mode, some older management
firmware might incorrectly notify interfaces of link changes while they
haven't requested the physical link configuration to be set.
This can create bizzare race conditions where unloading interfaces are
getting notified that the link is up.
Let the driver compensate - store the logical requested state of the link
and don't propagate notifications after protocol driver explicitly
requires the link to be unset.

When using INTa, ISR might be called before device is configured
for INTa [E.g., due to other device asserting the shared interrupt line],

later on. There's also an MSI-X issue due to this difference, although

Concurrent non-blocking slowpath ramrods can be completed
out-of-order on the completion chain. Recycling completed elements,
while previously sent elements are still completion pending,
can lead to overriding of active elements on the chain. Furthermore,
sending pending slowpath ramrods currently lacks the update of the
chain element physical pointer.
This patch:
* Ensures that ramrods are sent to the FW with
consecutive echo values.
* Handles out-of-order completions by freeing only first
successive completed entries.
* Updates the chain element physical pointer when copying
a pending element into a free element for sending.

The bonding driver saves a copy of slaves' original mac address and then
assigns whatever mac as needed to the slave, depending on mode. In at
least modes 5 and 6 (balance-tlb, balance-alb), it often ends up being the
mac address of another slave. On release from the bond, the original mac
address is supposed to get restored via a dev_set_mac_address() call in
the bonding driver's __bond_release_one() function, which calls the
slave's ndo_set_mac_address function, which for qlcnic, is
qlcnic_set_mac().
Now, this function tries to be somewhat intelligent and exit early if
you're trying to set the mac address to the same thing that is already
set. The problem here is that adapter->mac_addr isn't in sync with
netdev->dev_addr. The qlcnic driver still has the original mac stored in
adapter->mac_addr, while the bonding driver has updated netdev->dev_addr,
so qlcnic thinks we're trying to set the same address it already has.
I think the way to go here, since the function updates both netdev and
adapter's stored mac addresses, is to check if either of them doesn't
match the newly requested mac. Simply checking netdev's value only could
result in a similar mismatch and non-update, so look at both.

This module serves two main purposes:
1. It's responsible to contain all the common code that will be shared
between the various drivers that would be used with said line of
products. Flows such as chip initialization and de-initialization
fall under this category.
2. It would abstract the protocol-specific HW & FW components, allowing

This adds a very basic module without any protocol-specific bits.

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

Unfortunately, I didn't check to see where else this lock was used before
submitting that patch. This should take care of it for netxen_nic, as I
did a thorough search this time.
To recap from the original patch; although testing this driver with
DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled did not produce any traces,
it would be more prudent in the case of tx_clean_lock to use _bh
versions of spin_[un]lock, since this lock is manipulated in both
the process and softirq contexts.
This patch was tested for functionality and regressions with netperf
and DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled.

Driver keeps adding multicast addresses without deleting removed MACs and
worrying about adapters filter limit. This results into actual count of programmed
multicast addresses get accumulated over the time and overruns the adapter's
filter limit without putting device in ACCEPT_ALL_MULTI mode. This causes
newly added multicast traffic to fail after the sequence of addition - deletion
in certain pattern.
This issue is seen only when netdev's mcast list count is less than adapters
mcast filter limit.
e.g. If adapters multicast filter limit is 38 per function
then following sequence would result in multicast traffic failure for
newly added MACs.
- add less than 38 multicast MACs
- remove previously added multicast MACs
- add new multicast MACs (less than 38)

Currently qlge_update_hw_vlan_features() will always first put the
interface down, then update features and then bring it up again. But it
is possible to hit this code while the adapter is down and this causes a

This patch fixes it by skipping these down/up actions if the interface
is already down.

GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.
This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.
By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.

Pull networking updates from David Miller:
"Most notable changes in here:
1) By far the biggest accomplishment, thanks to a large range of
contributors, is the addition of multi-send for transmit. This is
the result of discussions back in Chicago, and the hard work of
several individuals.
Now, when the ->ndo_start_xmit() method of a driver sees
skb->xmit_more as true, it can choose to defer the doorbell
telling the driver to start processing the new TX queue entires.
skb->xmit_more means that the generic networking is guaranteed to
call the driver immediately with another SKB to send.
There is logic added to the qdisc layer to dequeue multiple
packets at a time, and the handling mis-predicted offloads in
software is now done with no locks held.
Finally, pktgen is extended to have a "burst" parameter that can
be used to test a multi-send implementation.
Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
virtio_net
Adding support is almost trivial, so export more drivers to
support this optimization soon.
I want to thank, in no particular or implied order, Jesper
Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
David Tat, Hannes Frederic Sowa, and Rusty Russell.

3) Allow adjusting the rx_copybreak threshold for a driver via
ethtool, and add rx_copybreak support to enic driver. From
Govindarajulu Varadarajan.
4) Significant enhancements to the generic PHY layer and the bcm7xxx
driver in particular (EEE support, auto power down, etc.) from
Florian Fainelli.
5) Allow raw buffers to be used for flow dissection, allowing drivers
to determine the optimal "linear pull" size for devices that DMA
into pools of pages. The objective is to get exactly the
necessary amount of headers into the linear SKB area pre-pulled,
but no more. The new interface drivers use is eth_get_headlen().

by-hand duplicated implementations) by Alexander Duyck and Eric

6) Support checksumming more smoothly and efficiently for
encapsulations, and add "foo over UDP" facility. From Tom

7) Add Broadcom SF2 switch driver to DSA layer, from Florian
Fainelli.
8) eBPF now can load programs via a system call and has an extensive

This device claims TSO support for vlans. It also allows a user to
control vlan acceleration offloading. As such, it is possible to turn
off vlan acceleration and configure a vlan which will continue to send
TSO traffic.
In such situation the packet passed down the the device will contain
a vlan header and skb->protocol will be set to ETH_P_8021Q.
The device assumes that skb->protocol contains network protocol
value and uses that value to set up TSO information.
This results in corrupted frames sent on the wire.
This patch extracts the protocol value correctly by using a
vlan_get_protocol() helper and corrects corrupt TSO frames.

o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed
to have a bandwidth of at least this value.
max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth
of up to this value.
o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced
which takes 4 arguments:
netdev, VF number, min_tx_rate, max_tx_rate
o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler.
o Drivers that currently implement ndo_set_vf_tx_rate should now call
ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth
greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet
implemented by driver.
o If user enters only one of either min_tx_rate or max_tx_rate, then,
userland should read back the other value from driver and set both
for IFLA_VF_RATE.
Drivers that have not yet implemented IFLA_VF_RATE should always
return min_tx_rate as 0 when read from ip tool.
o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then
IFLA_VF_RATE should override.
o Idea is to have consistent display of rate values to user.
o Usage example: -

Since commit 82dc3c63 ("net: introduce NAPI_POLL_WEIGHT")
netif_napi_add() produces an error message if a NAPI poll weight
greater than 64 is requested.
qlcnic requests the weight as large as 256 for some of its rings, and
smaller values for other rings. For instance in qlcnic_82xx_napi_add()
I think the intention was to give the tx+rx ring a bigger weight than
to rx-only rings, but it's actually doing the opposite. So I'm assuming
the weights do not really matter much.
Just use the standard NAPI weights for all rings.

Pull networking updates from David Miller:
"This is a re-do of the net-next pull request for the current merge
window. The only difference from the one I made the other day is that
this has Eliezer's interface renames and the timeout handling changes
made based upon your feedback, as well as a few bug fixes that have
trickeled in.
Highlights:
1) Low latency device polling, eliminating the cost of interrupt
handling and context switches. Allows direct polling of a network
device from socket operations, such as recvmsg() and poll().
Currently ixgbe, mlx4, and bnx2x support this feature.
Full high level description, performance numbers, and design in
commit 0a4db187a9 ("Merge branch 'll_poll'")
From Eliezer Tamir.
2) With the routing cache removed, ip_check_mc_rcu() gets exercised
more than ever before in the case where we have lots of multicast
addresses. Use a hash table instead of a simple linked list, from
Eric Dumazet.
3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
Marek Puzyniak, Michal Kazior, and Sujith Manoharan.
4) Support reporting the TUN device persist flag to userspace, from
Pavel Emelyanov.
5) Allow controlling network device VF link state using netlink, from
Rony Efraim.
6) Support GRE tunneling in openvswitch, from Pravin B Shelar.
7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
Daniel Borkmann and Eric Dumazet.
8) Allow controlling of TCP quickack behavior on a per-route basis,
from Cong Wang.
9) Several bug fixes and improvements to vxlan from Stephen
Hemminger, Pravin B Shelar, and Mike Rapoport. In particular,
support receiving on multiple UDP ports.
10) Major cleanups, particular in the area of debugging and cookie
lifetime handline, to the SCTP protocol code. From Daniel
Borkmann.
11) Allow packets to cross network namespaces when traversing tunnel
devices. From Nicolas Dichtel.
12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
manner akin to how we monitor real network traffic via ptype_all.
From Daniel Borkmann.
13) Several bug fixes and improvements for the new alx device driver,
from Johannes Berg.
14) Fix scalability issues in the netem packet scheduler's time queue,
by using an rbtree. From Eric Dumazet.
15) Several bug fixes in TCP loss recovery handling, from Yuchung
Cheng.
16) Add support for GSO segmentation of MPLS packets, from Simon
Horman.
17) Make network notifiers have a real data type for the opaque
pointer that's passed into them. Use this to properly handle
network device flag changes in arp_netdev_event(). From Jiri
Pirko and Timo Teräs.
18) Convert several drivers over to module_pci_driver(), from Peter
Huewe.
19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
O(1) calculation instead. From Eric Dumazet.
20) Support setting of explicit tunnel peer addresses in ipv6, just
like ipv4. From Nicolas Dichtel.
21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.
22) Prevent a single high rate flow from overruning an individual cpu
during RX packet processing via selective flow shedding. From
Willem de Bruijn.
23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
Dumazet.
24) Don't just drop GSO packets which are above the TBF scheduler's
burst limit, chop them up so they are in-bounds instead. Also
from Eric Dumazet.
25) VLAN offloads are missed when configured on top of a bridge, fix
from Vlad Yasevich.
26) Support IPV6 in ping sockets. From Lorenzo Colitti.
27) Receive flow steering targets should be updated at poll() time
too, from David Majnemer.
28) Fix several corner case regressions in PMTU/redirect handling due
to the routing cache removal, from Timo Teräs.
29) We have to be mindful of ipv4 mapped ipv6 sockets in
upd_v6_push_pending_frames(). From Hannes Frederic Sowa.
30) Fix L2TP sequence number handling bugs, from James Chapman."

qlge allocates chunks from a page that it maps and unmaps that page when
the last chunk is released. When the driver is unloaded or the card is
removed, all chunks are released and the page is unmapped for the last
chunk.
However, when the last chunk of a page is not allocated and the device
is removed, that page is not unmapped. In fact, its last reference is
not put and there's also a page leak. This bug prevents a device from
being properly hotplugged.
When the DMA API debug option is enabled, the following messages show
the pending DMA allocation after we remove the driver.
This patch fixes the bug by unmapping and putting the page from the ring
if its last chunk has not been allocated.
pci 0005:98:00.0: DMA-API: device driver has pending DMA allocations while released from device [count=1]
One of leaked entries details: [device address=0x0000000060a80000] [size=65536 bytes] [mapped with DMA_FROM_DEVICE] [mapped as page]

The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
cleanup in net-next to now pass cred structs around.
The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.
An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.
Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.
Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO
rewrite in 'net-next', mostly overlapping changes.

o Adapter provides communication channel between VF and PF.
Any control commands from the VF driver are sent to the PF driver
through this communication channel. PF driver validates the
commands before sending them to the adapter. Similarly PF driver
forwards any control command responses to the VF driver
through this communication channel. Adapter sends message pending
event to VF or PF when there is an outstanding response or a command
for VF or PF respectively. When a command or a response is sent over
a channel VF or PF cannot send another command or a response
until adapter sends a channel free event. Adapter allocates 1K area to
VF and PF each for this communication.
o Commands and responses are encapsulated in a header. Header determines
sequence id, number of fragments, fragment number etc.

I believe these error messages are already logged
on allocation failure by warn_alloc_failed and so
get a dump_stack on OOM.
Remove the unnecessary additional error logging.
Around these deletions:
o Alignment neatening.
o Remove unnecessary casts of dma_alloc_coherent.
o Hoist assigns from ifs.

This patch allows LRO aggregation on bonded devices that contain an
NX3031 device. It also adds a for_each_netdev_in_bond_rcu(bond, slave)
macro which executes for each slave that has bond as master.
V3: After testing and discussing this with Rajesh, I decided to keep the
vlan ip cache and just rename it to ip_cache since it will store bond
ip addresses too. A new master flag has been added to the ip cache to
denote that the address has been added because of a master device.
I've taken care of the enslave/release cases by checking for various
combinations of events and flags (e.g. netxen has a master, it's a
bond master and it's not marked as a slave means it is being enslaved
and is dev_open()ed in bond_enslave).
I've changed netxen_free_ip_list() to have a "master" parameter which
causes all IP addresses marked as master to be deleted (used when a
netxen is being released). I've made the patch use the new upper
device API as well. The following cases were tested:
- bond -> netxen
- vlan -> netxen
- vlan -> bond -> netxen
V2: Remove local ip caching, retrieve addresses dynamically and
restore them if necessary.
Note: Tested with NX3031 adapter.

Allow qlcnic to use the generic fdb handler when the driver options
are not enabled. Untill the driver is fully fixed, this allows
the use of the FDB interface with qlogic driver, but simply puts
the driver into promisc mode since the driver currently does not
support IFF_UNICAST_FLT.

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.
The semantic patch which is mostly the work of Peter Senna Tschudin is here:

Christoph Paasch found netxen could trigger a BUG in its dismantle
phase, in netxen_release_tx_buffer(), using full size TSO packets.
cmd_buf->frag_count includes the skb->data part, so the loop must
start at index 1 instead of 0, or else we can make an out
of bound access to cmd_buff->frag_array[MAX_SKB_FRAGS + 2]
Christoph provided the fixes in netxen_map_tx_skb() function.
In case of a dma mapping error, its better to clear the dma fields
so that we don't try to unmap them again in netxen_release_tx_buffer()

It is werid that qlge driver supports NETIF_F_TSO6 but
not NETIF_F_IPV6_CSUM. This also causes some kernel warning [1]
when VLAN device setups on a qlge interface.
I think the qlge hardware doesn't support NETIF_F_IPV6_CSUM,
so we have to just remove the NETIF_F_TSO6 flag.
After this patch, the TCP/IPv6 traffic becomes normal again,
no kernel warnings any more.
NOTE: I only tested it on 2.6.32 kernel, even if the upstream
kernel could fix this automatically (it is hard to track NETIF*
flags), removing it is also safe.

Flash template provides instructions to stop, restart and initalize the
firmware. These instructions are abstracted as a series of read, write and
poll operations on hardware registers. Register information and operation
specifics are not exposed to the driver. Driver reads the template from
flash and executes the instructions located at pre-defined offsets.
Template based firmware reset recovery and initialization mechanism minimize
driver changes as firmware evolves.

The function qlcnic_probe() return 0 for success and negative value
for most of its internal tests failures. There is one exception
that is error case going to err_out_free_netdev:. For this error case,
the function abort its success execution path, but returns non negative
value, making it difficult for a caller function to notice the error.
This patch fixes the error case that do not return negative value.
This was found by Coccinelle, but the code change was made by hand.
This patch is not robot generated.
A simplified version of the semantic match that finds this problem is
as follows: (http://coccinelle.lip6.fr/)

net/ipv6/route.c
This deals with a merge conflict between the net-next addition of the
inetpeer network namespace ops, and Thomas Graf's bug fix in
2a0c451ade which makes sure we don't
register /proc/net/ipv6_route before it is actually safe to do so.

The adapter->npars[] array has QLCNIC_MAX_PCI_FUNC elements. We
allocate it that way a few lines earlier in the function. So this test
is off by one.

o Use correct l3 (ETH_IP or ETH_IPV6)protcol in case
of inband vlan. Because of incorrect protcol type driver
was setting incorrect opcode. This resulted in adapter calculating
checksum incorrectly.
o Updated driver version to 5.0.29

o Linux stack estimates MSS from skb->len or skb_shinfo(skb)->gso_size.
In case of LRO skb->len is aggregate of len of number of packets hence MSS
obtained using skb->len would be incorrect. Incorrect estimation of recv MSS
would lead to delayed acks in some traffic patterns (which sends two or three
packets and wait for ack and only then send remaining packets). This leads to
drop in performance. Hence we need to set gso_size to MSS obtained from firmware.
o This is fixed recently in firmware hence the MSS is obtained based on
capability. If fw is capable of sending the MSS then only driver sets the gso_size.
