d9a58a782e xen/netfront: improve truesize tracking
Using RX_COPY_THRESHOLD is incorrect if the SKB is actually smaller
than that. We have already accounted for this in
NETFRONT_SKB_CB(skb)->pull_to so use that instead.

Fixes WARN_ON from skb_try_coalesce.

5e20a4b530 b43: Fix firmware loading when driver is built into the kernel
Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space would time
out. The original fix for b43 (commit 6b6fa58) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43 is built as a module;
however, it fails when the driver is compiled into the kernel.

This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. This driver
reads several firmware files - the remainder can be read synchronously.
On some test systems, the async read fails; however, a following synch
read works, thus the async failure falls through to the sync try.

2be7d22f06 wireless: add new wil6210 802.11ad 60GHz driver
This adds support for the 60 GHz 802.11ad Wilocity card
through a new driver, wil6210. Wilocity implemented the
firmware, QCA maintains the device driver.

Currently supported:

- STA: with security
- AP: limited to 1 connected STA, security disabled
- Monitor: due to a hardware/firmware limitation
  either control or non-control frames are monitored

Using a STA and AP with this drive, one can assemble
a fully functional BSS. Throughput of 1.2Gbps is achieved
with iperf.

The wil6210 cards have on-board flash memory for the
firmware, the cards comes pre-flashed and no firmware
download is required.

For more details see:

9c969d8ccb mwifiex: check wait_event_interruptible return value
wait_event_interruptible function returns -ERESTARTSYS if it's
interrupted by a signal. Driver should check the return value
and handle this case properly.

In mwifiex_wait_queue_complete() routine, as we are now checking
wait_event_interruptible return value, the condition check is not
required. Also, we have removed mwifiex_cancel_pending_ioctl()
call to avoid a chance of sending second command to FW by other path
as soon as we clear current command node. FW can not handle two
commands simultaneously.

9a6f7347f5 ath9k: Fix Kconfig for ATH9K_HTC
Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC.
Both uses common Atheros code from ath.ko and need ATH_COMMON.

However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not.
As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with
unresolved symbols.

This patch moves ATH_COMMON selection to the common part for both
ATH9K and ATH9K_HTC

7ffa592843 brcmsmac: Use udelay instead of usleep_range
wlc_lcnphy_rx_iq_cal_gain is called during initialization, i. e. when
executing brcms_up.
But brcms_up is called from brcms_ops_start while the latter holds a spin lock.
Thus, we cannot use usleep_range but have to use udelay.

This fixes:

6c653f6677 carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESH
Sean reported that as of 3.7, his AR9170 device no longer works
because the driver fails during initialization. He noted this
is due to:
"In carl9170/fw.c, ar->hw->wiphy is tagged with
NL80211_IFTYPE_MESH_POINT support if the firmware has Content
after Beacon Queuing. This is both in interface_modes and the
only iface_combinations entry.

If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw
removes NL80211_IFTYPE_MESH_POINT from interface_modes, but
not iface_combinations.

wiphy_register then checks to see if every interface type in
every interface combination is in interface_modes.
NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON
warning and it returns -EINVAL, giving up."

Unfortunately, the iface_combination (types) feature bitmap
in ieee80211_iface_limit is part of a const member in the
ieee80211_iface_combination struct. Hence, the MESH_POINT
feature flag can't be masked by wiphy_register in the
same way as interface_modes in ieee80211_register_hw.

9fdc6bef5f tuntap: dont use a private kmem_cache
Commit 96442e4242 (tuntap: choose the txq based on rxq)
added a per tun_struct kmem_cache.

As soon as several tun_struct are used, we get an error
because two caches cannot have same name.

Use the default kmalloc()/kfree_rcu(), as it reduce code
size and doesn't have performance impact here.

Latinoware 2012.
 
 There's a slightly non-trivial merge in virtio-net, as we cleaned up the
 virtio add_buf interface while DaveM accepted the mq virtio-net patches.
 
 You can see my solution in my pending-rebases branch, if that helps, but I
 know you love merging:

793dad94e7 RDMA/cxgb4: Fix bug for active and passive LE hash collision path
Retries active opens for INUSE errors.

Logs any active ofld_connect_wr error replies.

Sends ofld_connect_wr on same ctrlq. It needs to go  on the same control txq as
regular CPL active/passive messages.

Retries on active open replies with EADDRINUSE.

Uses active open fw wr only if active filter region is set.

Adds stat for ofld_connect_wr failures.

This patch also adds debugfs file to show endpoints.

It establishes passive open connection through firmware work request. Passive
open connection will go through this path as now instead of listening server we
create a server filter which will redirect the incoming SYN packet to the
offload queue. After this driver tries to establish the connection using
firmware work request.

It enables establishing active open connection using fw_ofld_connection work
request when cpl_act_open_rpl says TCAM full error which may be because
of LE hash collision. Current support is only for IPv4 active open connections.

Sets ntuple bits in active open requests. For T4 firmware greater than 1.4.10.0
ntuple bits are required to be set.

Adds nocong and enable_ecn module parameter options.

Above commit may introduce a race between cp_interrupt and dev_close
/ change MTU / dev_open up state. Changes cp_interrupt to tolerate
this.  Change spin_locking in cp_interrupt to avoid possible
but unobserved race.
