      net/mlx4_core: Load the Eth driver first · f24f790f
      由 Or Gerlitz 提交于 
      When running in SRIOV mode, VM that is assigned with a non-provisioned
Ethernet VFs get themselves a random mac when the Eth driver starts. In
this case, if the IB driver startup code that deals with RoCE runs first,
it will use a zero mac as the source mac for the Para-Virtual CM MADs
which is buggy. To handle that, we change the order of loading.

      net/mlx4_core: Fix slave id computation for single port VF · 0254bc82
      由 Matan Barak 提交于 
      The code that deals with computing the slave id based on a given GID
gave wrong results when the number of single port VFs wasn't the
same for port 1 vs. port 2 and the relevant VF is single ported on
port 2. As a result, incoming CM MADs were dispatched to the wrong VF.
Fixed that and added documentation to clarify the computation steps.

      由 Jack Morgenstein 提交于 
      When using single ported VFs and the VF is using port 2, we need
to adjust the port accordingly (change it from 1 to 2).

      net: cdc_ncm: fix buffer overflow · 9becd707
      由 Bjørn Mork 提交于 
      Commit 4d619f62 ("net: cdc_ncm: no point in filling up the NTBs
if we send ZLPs") changed the padding logic for devices with the ZLP
flag set.  This meant that frames of any size will be sent without
additional padding, except for the single byte added if the size is
a multiple of the USB packet size. But if the unpadded size is
identical to the maximum frame size, and the maximum size is a
multiplum of the USB packet size, then this one-byte padding will
overflow the buffer.

Prevent padding if already at maximum frame size, letting usbnet
transmit a ZLP instead in this case.

      vsock: Make transport the proto owner · 2c4a336e
      由 Andy King 提交于 
      Right now the core vsock module is the owner of the proto family. This
means there's nothing preventing the transport module from unloading if
there are open sockets, which results in a panic. Fix that by allowing
the transport to be the owner, which will refcount it properly.

Includes version bump to 1.0.1.0-k

Passes checkpatch this time, I swear...

      John W. Linville says:

====================
pull request: wireless 2014-05-01

Please pull the following batch of fixes intended for the 3.15 stream!

For the Bluetooth bits, Gustavo says:

"Some fixes for 3.15. There is a revert for the intel driver, a new
device id, and two important SSP fixes from Johan."

On top of that...

Ben Hutchings gives us a fix for an unbalanced irq enable in an
rtl8192cu error path.

Colin Ian King provides an rtlwifi fix for an uninitialized variable.

Felix Fietkau brings a pair of ath9k fixes, one that corrects a
hardware initialization value and another that removes an (unnecessary)
flag that was being used in a way that led to a software tx queue
hang in ath9k.

Gertjan van Wingerde pushes a MAINTAINERS change to remove himself
from the rt2x00 maintainer team.

Hans de Goede fixes a brcmfmac firmware load hang.

Larry Finger changes rtlwifi to use the correct queue for V0 traffic
on rtl8192se.

Rajkumar Manoharan corrects a race in ath9k driver initialization.

Stanislaw Gruszka fixes an rt2x00 bug in which disabling beaconing
once on USB devices led to permanently disabling beaconing for those
devices.

Tim Harvey provides fixes for a pair of ath9k issues that can lead
to soft lockups in that driver.

Please let me know if there are problems!

      ath9k: remove tid->paused flag · 62e54dbb
      由 Felix Fietkau 提交于 
      There are some corner cases where the driver could get stuck with a full
tid queue that is paused, leading to a software tx queue hang.

Since the tx queueing rework, pausing per-tid queues on aggregation
session setup is no longer necessary. The driver will assign sequence
numbers to buffered frames when a new session is established, in order
to get the correct starting sequence number.

mac80211 prevents new frames from entering the queue during setup.

      ath9k_hw: do not lower ANI setting below default on AR913x · ae9c25a1
      由 Felix Fietkau 提交于 
      When the amount of noise fluctuates strongly, low immunity settings
can sometimes disrupt signal detection on AR913x chips. When that
happens, no OFDM/CCK errors are reported anymore, and ANI tunes the
radio to the lowest immunity settings.
Usually rx/tx fails as well in that case.

To fix this, keep noise immunity settings at or above ANI default level,
which will keep radio parameters at or above INI values.
