Due to obviously missing braces, EESR.TABT (transmit abort) interrupt may be
reported even if it hasn't happened, just when EESR.TWB (transmit descriptor
write-back) interrupt happens. Luckily (?), EESR.TWB is disabled by the driver
via the TRIMD register and all the interrupt masks, so that transmit abort is
never actually logged...
Put the braces where they should be and fix the incoherent comment, while at it.

EESR.RFE (receive FIFO overflow) interrupt is enabled by the driver on all SoCs
and sh_eth_error() handles it but it's not present in any initializer/assignment
of the 'eesr_err_check' field of 'struct sh_eth_cpu_data'. This leads to that
interrupt not being handled and cleared, and finally to disabling IRQ and the
driver being non-functional.
Modify DEFAULT_EESR_ERR_CHECK macro and all explicit initializers of the above
mentioned field to contain the EESR.RFE bit. Remove useless backslashes from the
initializers, while at it.

If we disable all of the net interfaces, and enable
un-lo interface before lo interface, we already allocated
the addrconf dst in ipv6_add_addr. So we shouldn't allocate
it again when we enable lo interface.

MD5 key lookups on a given TCP socket were being performed
incorrectly. This fix alters parameter inputs to the MD5
lookup function tcp_md5_do_lookup, which is called by functions
tcp_md5_do_add and tcp_md5_do_del. Specifically, the change now
inputs the correct address and address family required to make
a proper lookup.

Due to some hardware integration issue, CPSW sliver modules requires a
reset across suspend/resume cycle for a successful clock gating to
CPGMAC (CPSW and Davinci MDIO) in AM335x PG1.0.
This issue is fixed in PG2.x, though to support suspend/resume on PG1.0
this reset is required.

Commits 4c09eed9 (net: fec: Enable imx6 enet checksum acceleration) and
baa70a5c (net: fec: enable pause frame to improve rx prefomance for 1G
network) introduced functionality into the FEC driver which is not
supported on MCF5272. The registers used to implement this functionality
do not exist on MCF5272. Since register defines for MCF5272 are separate
from register defines for other chips, building images for MCF5272 fails
as follows.
fec_main.c: In function 'fec_restart':
fec_main.c:520:8: error: 'FEC_RACC' undeclared (first use in this function)

fec_main.c:591:3: error: 'FEC_OPD' undeclared (first use in this function)
Adding the missing register defines is not an option, since the registers
do not exist on MCF5272. Disable the added functionality for MCF5272 builds.

Since my commit 3713b4e364 ("nl80211: allow splitting wiphy
information in dumps"), nl80211_dump_wiphy() uses the global
nl80211_fam.attrbuf for parsing the incoming data. This wouldn't
be a problem if it only did so on the first dump iteration which
is locked against other commands in generic netlink, but due to
space constraints in cb->args (the needed state doesn't fit) I
decided to always parse the original message. That's racy though
since nl80211_fam.attrbuf could be used by some other parsing in
generic netlink concurrently.
For now, fix this by allocating a separate parse buffer (it's a
bit too big for the stack, currently 1448 bytes on 64-bit). For
-next, I'll change the code to parse into the global buffer in
the first round only and then allocate a smaller buffer to keep
the data in cb->args.

vxlan: only migrate dynamic FDB entries
was not correct because it is checking flag about type of FDB
entry, rather than the state (dynamic versus static). The confusion
arises because vxlan is reusing values from bridge, and bridge is
reusing values from neighbour table, and easy to get lost in translation.

This patch fixes the problem by unregistering the netdev in the error path.

As part of the push to add 802.1ad server provider tagging support to the
kernel the VLAN features flags were renamed. Unfortunately the kernel name
for the VLAN hardware acceleration features that the kernel shows user space
was included in the rename, which broke ethtool (txvlan and rxvlan options
do not work). This patch restores the original names, i.e. the original ABI.
If we wanted to make clear to users that we are refering to CTAGs we can
always change ethtool's short_name and long_name for these features (for
example something along the lines of txvlan -> txvlan-ctag, tx-vlan-offload ->
tx-vlan-ctag-offload).

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless
John W. Linville says:
====================
This will probably be the last batch of wireless fixes intended
for 3.10. Many of these are one- or two-liners, and a couple of
others are mostly relocating existing code to avoid races or to
limit the code to effecting specific hardware, etc.
The mac80211 fixes have a couple of exceptions to the above.
Regarding those, Johannes says:
"Following davem's complaint about my patch, here's a new pull request
w/o the patch he was complaining about, but instead with the const
fix rolled into the fix.
I have a fix for radar detection, one for rate control and a workaround
for broken HT APs which is a regression fix because we didn't rely
on them to be correct before."
Johannes also sends some iwlwifi fixes:
"I picked up Nikolay's patch for the chain noise calibration bug
that seems to have been there forever, a fix from Emmanuel for
setting TX flags on BAR frames and a fix of my own to avoid printing
request_module() errors if the kernel isn't even modular. We also
have our own version of Stanislaw's fix for rate control."
Along with those...
Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU
value is set to too small of a value.
Arend van Spriel sends a revised brcmsmac bug that fixes a regression
caused by a bad return value in an earlier patch. He also sends a
brcmfmac fix to avoid an oops when loading the driver at boot.
Daniel Drake fixes a race condition in btmrvl that causes hangs on
suspend for OLPC hardware.
Johan Hedberg adds a check to avoid sending a
HCI_Delete_Stored_Link_Key command to devices that don't support them,
avoiding some scary looking log spam.
Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates
higher than 1Mb/s on older wireless networks. He also sends an rt2x00
fix to reinstate older tx power handling behavior for some devices
that didn't work well with the current code.

When initialization within brcmf_bus_start() fails on steps
before the brcmf_net_attach() the net_device for the primary
interface needs to be freed.

There is currently a race condition in the btmrvl_remove_card() which
is causing hangs on suspend for OLPC. When the race occurs,
kthread_stop() never returns.
The problem is that btmrvl_service_main_thread() calls kthread_should_stop()
and then does a fair number of things before restarting the loop and
sleeping.
If the thread gets stopped after kthread_should_stop() is checked, but
before the sleep happens, the thread will go to sleep and won't necessarily
be woken up.
Move the kthread_should_stop() check into a race-free place.

Even though the HCI_Delete_Stored_Link_Key command is mandatory for 1.1
and later controllers some controllers do not seem to support it
properly as was witnessed by one Broadcom based controller:
< HCI Command: Delete Stored Link Key (0x03|0x0012) plen 7
bdaddr 00:00:00:00:00:00 all 1
> HCI Event: Command Complete (0x0e) plen 4
Delete Stored Link Key (0x03|0x0012) ncmd 1
status 0x11 deleted 0
Error: Unsupported Feature or Parameter Value
Luckily this same controller also doesn't list the command in its
supported commands bit mask (counting from 0 bit 7 of octet 6):
< HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0
> HCI Event: Command Complete (0x0e) plen 68
Read Local Supported Commands (0x04|0x0002) ncmd 1
status 0x00
Commands: ffffffffffff1ffffffffffff30fffff3f
Therefore, it makes sense to move sending of HCI_Delete_Stored_Link_Key
to after receiving the supported commands response and to only send it
if its respective bit in the mask is set. The downside of this is that
we no longer send the HCI_Delete_Stored_Link_Key command for Bluetooth
1.1 controllers since HCI_Read_Local_Supported_Command was introduced in
version 1.2, but this is an acceptable penalty as the command in
question shouldn't affect critical behavior.

If a too small MTU value is set with ioctl(HCISETACLMTU) or by a bogus
controller, memory corruption happens due to a memcpy() call with
negative length.
Fix this crash on either incoming or outgoing connections with a MTU
smaller than L2CAP_HDR_SIZE + L2CAP_CMD_HDR_SIZE:

First step of chain noise calibration process had disable flag
check inverted. Chain noise calibration never started because
of this.
Tested on intel 5300 with two antennas attached. The driver
correctly disabled one chain.

If the opmode modules aren't modular, there's no point in
printing an error message that request_module() failed.
This will happen because the probe runs during iwlwifi's
init and the opmode is only added during its init.

When a CAC is running and stop_ap is called (e.g. when hostapd is killed
while performing CAC), the CAC must be aborted immediately.
Otherwise ieee80211_stop_ap() will try to stop it when it's too late -
wdev->channel is already NULL and the abort event can not be generated.

There are some APs, notably 2G/3G/4G Wifi routers, specifically the
"Onda PN51T", "Vodafone PocketWiFi 2", "ZTE MF60" and a similar
T-Mobile branded device [1] that erroneously don't include all the
needed information in (re)association response frames. Work around
this by assuming the information is the same as it was in the
beacon or probe response and using the data from there instead.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58881.

Note that this requires marking the first ieee802_11_parse_elems()
argument const, otherwise we'd get a compiler warning.

rt2800: use BBP_R1 for setting tx power
unfortunately does not work well with RT5390 and RT3290 chips as they
require different temperature compensation TX power settings (TSSI
tuning). Since that commit make wireless connection very unstable on
those chips, restore previous behavior to fix regression. Once we
implement proper TSSI tuning on 5390/3290 we can restore back setting
TX power by BBP_R1 register for those chips.

This patch fixes a regression introduced by:
commit 6da3b6c48d79da96a36c2632053cf4f53bf48fb2
Author: Hauke Mehrtens <hauke@hauke-m.de>
Date: Sun Mar 24 01:45:52 2013 +0100
brcmsmac: remove brcms_bss_cfg->associated
The regression behaviour was described on mailing list.
http://mid.gmane.org/5197DC4F.7030503@broadcom.com:
"On laptop I installed kernel with brcmsmac compiled as
module. It comes up and associates during boot, but after
logging in there is no connectivity. Triggering reassoc
gives connectivity for some time, but after a while (1-2 min)
it stops."
Before the mentioned commit the return value of
the function brcms_c_ps_allowed() was always false,
which is desired behaviour as power-save is not
supported at the moment. Therefor, the function is
changed to just return false instead of simply
reverting the mentioned commit.

====================
The following patchset contains Netfilter fixes. They are targeted to the
TCP option targets, that have receive some scrinity in the last week. The
changes are:
* Fix TCPOPTSTRIP, it stopped working in the forward chain as tcp_hdr
uses skb->transport_header, and we cannot use that in the forwarding
case, from myself.
* Fix default IPv6 MSS in TCPMSS in case of absence of TCP MSS options,
from Phil Oester.
* Fix missing fragmentation handling again in TCPMSS, from Phil Oester.

As a followup to commit 409b545a ("netfilter: xt_TCPMSS: Fix violation
of RFC879 in absence of MSS option"), John Heffner points out that IPv6
has a higher MTU than IPv4, and thus a higher minimum MSS. Update TCPMSS
target to account for this, and update RFC comment.
While at it, point to more recent reference RFC1122 instead of RFC879.

In (bc6bcb5 netfilter: xt_TCPOPTSTRIP: fix possible mangling beyond

cannot assume that skb->transport_header is set for non-local packets.
