Just some minor conflicts between the wireless-next changes
and Joe Perches's "extern" removal from function prototypes
in header files.
John W. Linville says:
====================
Regarding the Bluetooth bits, Gustavo says:
"The big work here is from Marcel and Johan. They did a lot of work
in the L2CAP, HCI and MGMT layers. The most important ones are the
addition of a new MGMT command to enable/disable LE advertisement
and the introduction of the HCI user channel to allow applications
to get directly and exclusive access to Bluetooth devices."
As to the ath10k bits, Kalle says:
"Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's
just too much to support it. Michal added support for the new firmware
interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are
minor fixes or cleanups."
And also:
"Major changes are:
* throughput improvements including aligning the RX frames correctly and
optimising HTT layer (Michal)
* remove qca98xx hw1.0 support (Bartosz)
* add support for firmware version 999.999.0.636 (Michal)
* firmware htt statistics support (Kalle)
* fix WEP in AP and IBSS mode (Marek)
* fix a mutex unlock balance in debugfs file (Shafi)
And of course there's a lot of smaller fixes and cleanup."
For the wl12xx bits, Luca says:
"Here are some patches intended for 3.13. Eliad is upstreaming a bunch
of patches that have been pending in the internal tree. Mostly bugfixes
and other small improvements."
Along with that...
Arend and friends bring us a batch of brcmfmac updates, Larry Finger
offers some rtlwifi refactoring, and Sujith sends the usual batch of
ath9k updates. As usual, there are a number of other small updates
from a variety of players as well.

Although we do not yet enable multiple PFs per port, it is possible
that a board will be reconfigured to enable them while the driver has
not yet been updated to fully support this.
The most obvious problem is that multiple functions may try to set
conflicting link settings. But we will also run into trouble if the
firmware doesn't consider us fully trusted. So, abort probing unless
both the LinkCtrl and Trusted flags are set for this function.

Recognise the new Packet Memory and RX Data Path counters.
The following counters are added:
rx_pm_{trunc,discard}_bb_overflow - burst buffer overflowed. This should not
occur if BB correctly configured.
rx_pm_{trunc,discard}_vfifo_full - not enough space in packet memory. May
indicate RX performance problems.
rx_pm_{trunc,discard}_qbb - dropped by 802.1Qbb early discard mechanism.
Since Qbb is not supported at present, this should not occur.
rx_pm_discard_mapping - 802.1p priority configured to be dropped. This should
not occur in normal operation.
rx_dp_q_disabled_packets - packet was to be delivered to a queue but queue is
disabled. May indicate misconfiguration by the driver.
rx_dp_di_dropped_packets - parser-dispatcher indicated that a packet should be
dropped.
rx_dp_streaming_packets - packet was sent to the RXDP streaming bus, ie. a
filter directed the packet to the MCPU.
rx_dp_emerg_{fetch,wait} - RX datapath had to wait for descriptors to be
loaded. Indicates performance problems but not drops.
These are only provided if the MC firmware has the
PM_AND_RXDP_COUNTERS capability. Otherwise, mask them out.

Previously, efx_ef10_stat_mask returned a static const unsigned long[], which
meant that each possible mask had to be declared statically with
STAT_MASK_BITMAP. Since adding a condition would double the size of the
decision tree, we now create the bitmask dynamically.
To do this, we have two functions efx_ef10_raw_stat_mask, which returns a u64,
and efx_ef10_get_stat_mask, which fills in an unsigned long * argument.

This patch allows (optionally, via ethtool) the atl1e NIC to:
- Receive bad frames (runt, bad-fcs, etc..)
- Receive full frames without stripping the FCS.
This has been tested on my board by injecting runt and bad-fcs
frames with a FPGA-based device.
The particular scenario of receiving very short frames (<4 bytes)
without passing FCS to the upper layer has been also tested:
This could be potentially dangerous because the driver performs a
4 byte subtraction on the frame length, but I finally have NOT
added anything to avoid this because it seems the NIC always
discards frames so much short..
If someone still have some reason to worry about this, please
tell me.. I will add an explicit SW check..

This patch adds two new hash policy modes which use skb_flow_dissect:
3 - Encapsulated layer 2+3
4 - Encapsulated layer 3+4
There should be a good improvement for tunnel users in those modes.
It also changes the old hash functions to:
hash ^= (__force u32)flow.dst ^ (__force u32)flow.src;
hash ^= (hash >> 16);
hash ^= (hash >> 8);
Where hash will be initialized either to L2 hash, that is
SRCMAC[5] XOR DSTMAC[5], or to flow->ports which should be extracted
from the upper layer. Flow's dst and src are also extracted based on the
xmit policy either directly from the buffer or by using skb_flow_dissect,
but in both cases if the protocol is IPv6 then dst and src are obtained by
ipv6_addr_hash() on the real addresses. In case of a non-dissectable
packet, the algorithms fall back to L2 hashing.
The bond_set_mode_ops() function is now obsolete and thus deleted
because it was used only to set the proper hash policy. Also we trim a
pointer from struct bonding because we no longer need to keep the hash
function, now there's only a single hash function - bond_xmit_hash that
works based on bond->params.xmit_policy.
The hash function and skb_flow_dissect were suggested by Eric Dumazet.
The layer names were suggested by Andy Gospodarek, because I suck at
semantics.

Recently grabbed this report:
https://bugzilla.redhat.com/show_bug.cgi?id=1005567
Of an issue in which the bonding driver, with an attached vlan encountered the
following errors when bond0 was taken down and back up:
dummy1: promiscuity touches roof, set promiscuity failed. promiscuity feature of
device might be broken.
The error occurs because, during __bond_release_one, if we release our last
slave, we take on a random mac address and issue a NETDEV_CHANGEADDR
notification. With an attached vlan, the vlan may see that the vlan and bond
mac address were in sync, but no longer are. This triggers a call to dev_uc_add
and dev_set_rx_mode, which enables IFF_PROMISC on the bond device. Then, when
we complete __bond_release_one, we use the current state of the bond flags to
determine if we should decrement the promiscuity of the releasing slave. But
since the bond changed promiscuity state during the release operation, we
incorrectly decrement the slave promisc count when it wasn't in promiscuous mode
to begin with, causing the above error
Fix is pretty simple, just cache the bonding flags at the start of the function
and use those when determining the need to set promiscuity.
This is also needed for the ALLMULTI flag

There was a bug that netback routines netbk/xenvif_skb_count_slots and
netbk/xenvif_gop_frag_copy disagreed with each other, which caused
netback to push wrong number of responses to netfront, which caused
netfront to eventually crash. The bug was fixed in 6e43fc04a
("xen-netback: count number required slots for an skb more carefully").
Commit 6e43fc04a focused on backport-ability. The drawback with the
existing packing scheme is that the ring is not used effeciently, as
stated in 6e43fc04a.
skb->data like:
| 1111|222222222222|3333 |
is arranged as:
|1111 |222222222222|3333 |
If we can do this:
|111122222222|22223333 |
That would save one ring slot, which improves ring effeciency.
This patch effectively reverts 6e43fc04a. That patch made count_slots
agree with gop_frag_copy, while this patch goes the other way around --
make gop_frag_copy agree with count_slots. The end result is that they
still agree with each other, and the ring is now arranged like:
|111122222222|22223333 |
The patch that improves packing was first posted by Xi Xong and Matt
Wilson. I only rebase it on top of net-next and rewrite commit message,
so I retain all their SoBs. For more infomation about the original bug
please refer to email listed below and commit message of 6e43fc04a.

When a packet is passed from mac80211 to the driver with the
IEEE80211_TX_CTL_PS_RESPONSE flag set, it bypasses the normal driver
internal queueing and goes directly to the UAPSD queue.
When that happens, packets that are part of a BlockAck session still
need to be tracked as such inside the driver, otherwise it will create
discrepancies in the receiver BA reorder window, causing traffic stalls.
This only happens in AP mode with powersave-enabled clients.

601216e "mwifiex: process RX packets in SDIO IRQ thread directly"
introduced a command timeout issue which can be reproduced easily on
an AM33xx platform using a test application written by Daniel Mack:
https://gist.github.com/zonque/6579314
mwifiex_main_process() is called from both the SDIO handler and
the workqueue. In case an interrupt occurs right after the
int_status check, but before updating the mwifiex_processing flag,
this interrupt gets lost, resulting in a command timeout and
consequently a card reset.
Let main_proc_lock protect both int_status and mwifiex_processing
flag. This fixes the interrupt lost issue.

Under this mode the chip is powered on including sdio
but no FW is downloaded and run, interrupts are not enabled, etc...
This mode is intended to allow RTTT to bridge sdio as a transport

Driver only provides sdio access using the dev_mem debugfs file.

Start a ROC on the AP channel beforing sending the authentication reply
to a connecting STA. This ROC is held up to 1 second via a timer. If the
station is authorized and added by mac80211, the ROC is extended until
the station is fully authorized.
We make sure not to ROC twice when several stations are connecting in
parallel and to only release the ROC when both the pending-reply timer
and the STA-state callbacks do not require it.

In the flexcan_chip_start() function first the flexcan core is going through
the soft reset sequence, then the RX FIFO is enabled.
With the hardware is put into FIFO mode, message buffers 1...7 are reserved by
the FIFO engine. The remaining message buffers are in reset default values.
This patch removes the bogus initialization of the message buffers, as it
causes an imprecise external abort on imx6.

After commit 1f718f0f4f ("bonding: populate
neighbour's private on enslave"), we've moved the unlinking of the slave
to the earliest position possible - so that nobody will see an
half-uninited slave.
However, bond_3ad_unbind_slave() relied that, even while removing the last
slave, it is still accessible - via __get_first_agg() (and, eventually,
bond_first_slave()).
Fix that by verifying if the aggregator return is an actual aggregator, but
not NULL.

After commit 1f718f0f4f ("bonding: populate
neighbour's private on enslave"), we've moved the actual 'linking' in the
end of the function - so that, once linked, the slave is ready to be used,
and is not still in the process of enslaving.
However, 802.3ad verified if it's the first slave by looking at the
if (bond_first_slave(bond) == new_slave)
which, because we've moved the linking to the end, became broken - on the
first slave bond_first_slave(bond) returns NULL.
Fix this by verifying if the prev_slave, that equals bond_last_slave(), is
actually populated - if it is - then it's not the first slave, and vice
versa.
