7a6cdb8cfe net: ethernet: qlogic: qlcnic: Remove duplicate object file from Makefile
In the Makefile, qlcnic_minidump.o is included twice in the list of
object files linked into qlcnic.o.

This change removes the superfluous include.

db56958127 wan: wanxl: Remove typedefs from struct names
The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedefs for
port_t, card_status_t and card_t. Also, the names of the structs
are changed to drop the _t, to make the name look less typedef-like.

The following Coccinelle semantic patch detects two cases and a
similar one detects the case for card_t.

0d5501c1c8 net: Always untag vlan-tagged traffic on input.
Currently the functionality to untag traffic on input resides
as part of the vlan module and is build only when VLAN support
is enabled in the kernel.  When VLAN is disabled, the function
vlan_untag() turns into a stub and doesn't really untag the
packets.  This seems to create an interesting interaction
between VMs supporting checksum offloading and some network drivers.

There are some drivers that do not allow the user to change
tx-vlan-offload feature of the driver.  These drivers also seem
to assume that any VLAN-tagged traffic they transmit will
have the vlan information in the vlan_tci and not in the vlan
header already in the skb.  When transmitting skbs that already
have tagged data with partial checksum set, the checksum doesn't
appear to be updated correctly by the card thus resulting in a
failure to establish TCP connections.

The following is a packet trace taken on the receiver where a
sender is a VM with a VLAN configued.  The host VM is running on
doest not have VLAN support and the outging interface on the
host is tg3:
10:12:43.503055 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q
(0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27243,

    10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect
-> 0x48d9), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val
4294837885 ecr 0,nop,wscale 7], length 0
10:12:44.505556 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q
(0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27244,
offset 0, flags [DF], proto TCP (6), length 60)
    10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect

4294838888 ecr 0,nop,wscale 7], length 0

This connection finally times out.

I've only access to the TG3 hardware in this configuration thus have
only tested this with TG3 driver.  There are a lot of other drivers
that do not permit user changes to vlan acceleration features, and
I don't know if they all suffere from a similar issue.

The patch attempt to fix this another way.  It moves the vlan header
stipping code out of the vlan module and always builds it into the
kernel network core.  This way, even if vlan is not supported on
a virtualizatoin host, the virtual machines running on top of such
host will still work with VLANs enabled.

Netfilter fixes for net

The following patchset contains fixes for your net tree, they are:

1) Unitialize the set element key and data from the commit path,
   otherwise this leaks chain refcount if the transaction is aborted,
   reported by Thomas Graf.

2) Fix crash when updating chains without no counters in nf_tables,
   this slipped through in the new transaction infrastructure, reported
   by Matteo Croce.

3) Replace all mutex_lock_interruptible() by mutex_lock() in the Netfilter
   tree, suggested by Patrick McHardy. This implicitly fixes the problem
   that Eric Dumazet reported in: http://patchwork.ozlabs.org/patch/373076/

   nf_tables if the transaction cannot be allocated, from Julia Lawall.

* Driver was previously not aware of what DCBx version was negotiated by
  firmware, this could lead to DCB app table  in kernel or in firmware being
  populated wrong  since IEEE/CEE used different formats made clear by above
  mentioned commit
* Driver was missing a couple of state transitions that could be caused
  by other drivers that use chelsio hardware, resulting in incorrect behaviour
  (the change that addresses this also flips the state machine to switch on
   state instead of transition, hope this is okay in current window)
* Prio queue info & tsa is no longer thrown away

f1f02fa4f1 net: ucc_geth: make probe consistently acquire a reference to the phy node
When the driver attaches to a device that has a phy handle the probe
routine returns with a reference to that node. This reference is
correctly dropped in the error path and the remove function. In the
fixed phy case however no reference is acquired and so the error path
might drop a reference the driver isn't holding. Fix that by getting a
reference to the MAC.

fa310789a4 net: ucc_geth: drop acquired references in probe error path and remove
The ucc_geth_probe function assigns to ug_info->tbi_node and
ug_info->phy_node a value returned by of_parse_phandle which returns a
new reference. Put this reference again in the error path of
ucc_geth_probe and when removing the device.

129cc83a0b net: fs_enet: fix reference counting for phy_node
Make sure that fs_enet_probe is left with a reference to the phy node.
In the presence of a phy handle this is already the case as
of_parse_phandle returns a reference. In the fixed phy case a call to
of_node_get is necessary. Otherwise the error path and remove function
drop a reference the driver isn't holding.

For the fixed phy setup make sure to not overwrite a valid value of

holding a reference.

Also add the corresponding of_node_put in the error path and the remove

abac0d3f80 drivers/net: Remove typedef axnet_dev_t
The Linux kernel coding style guidelines suggest not using typedefs

4e48ed883c netlink: reset network header before passing to taps
netlink doesn't set any network header offset thus when the skb is
being passed to tap devices via dev_queue_xmit_nit(), it emits klog
false positives due to it being unset like:

  ...
  [  124.990397] protocol 0000 is buggy, dev nlmon0
  [  124.990411] protocol 0000 is buggy, dev nlmon0
  ...

So just reset the network header before passing to the device; for
packet sockets that just means nothing will change - mac and net
offset hold the same value just as before.

6f2c9bd85e net: gianfar: fix reference counting for phy_node
The line before the changed if condition is:

	priv->phy_node = of_parse_phandle(np, "phy-handle", 0);

. If this call succeeds priv->phy_node must not be overwritten in the if
block; otherwise the reference to the node returned by of_parse_phandle
is lost. So add a check that the if block isn't executed in this case.

Furthermore in the fixed phy case no reference is aquired for phy_node
resulting in an of_node_put without holding a reference. To fix that,
get a reference on the MAC dt node.
