During traffic when DCB is enabled, it is possible for multiple instances
of statistics queries to be sent to the chip - this may cause the FW to assert.

This patch prevents the sending of an additional instance of statistics query
while the previous query hasn't completed.

This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.

  commit 230718bd net: qmi_wwan: bind to both control and data interface

changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function.  The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.

The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended.  Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.

gred_dequeue() and gred_drop() do not seem to get called when the
queue is empty, meaning that we never start idling while in WRED
mode. And since qidlestart is not stored by gred_store_wred_set(),
we would never stop idling while in WRED mode if we ever started.
This messes up the average queue size calculation that influences
packet marking/dropping behavior.

Now, we start WRED mode idling as we are removing the last packet
from the queue. Also we now actually stop WRED mode idling when we
are enqueuing a packet.

q->vars.qavg is a Wlog scaled value, but q->backlog is not. In order
to pass q->vars.qavg as the backlog value, we need to un-scale it.
Additionally, the qave value returned via netlink should not be Wlog
scaled, so we need to un-scale the result of red_calc_qavg().

This caused artificially high values for "Average Queue" to be shown
by 'tc -s -d qdisc', but did not affect the actual operation of GRED.

In the current rxhash calculation function, while the
sorting of the ports/addrs is coherent (you get the
same rxhash for packets sharing the same 4-tuple, in
both directions), ports and addrs are sorted
independently. This implies packets from a connection
between the same addresses but crossed ports hash to
the same rxhash.

For example, traffic between A=S:l and B=L:s is hashed
(in both directions) from {L, S, {s, l}}. The same
rxhash is obtained for packets between C=S:s and D=L:l.

This patch ensures that you either swap both addrs and ports,
or you swap none. Traffic between A and B, and traffic
between C and D, get their rxhash from different sources
({L, S, {l, s}} for A<->B, and {L, S, {s, l}} for C<->D)

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem

John W. Linville says:

====================
Please pull these fixes intended for 3.6.  There are more commits
here than I would like -- I got a bit behind while I was stalking
Steven Rostedt in San Diego last week...  I'll slow it down after this!

There are a couple of pulls here.  One is from Johannes:

"Please pull (according to the below information) to get a few fixes.

 * a fix to properly disconnect in the driver when authentication or
   association fails
 * a fix to prevent invalid information about mesh paths being reported
   to userspace
 * a memory leak fix in an nl80211 error path"

The other comes via Gustavo:

"A few updates for the 3.6 kernel. There are two btusb patches to add
more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO()
macro and another one that add a new device id for a Sony Vaio laptop,
one fix for a user-after-free and, finally, two patches from Vinicius
to fix a issue in SMP pairing."

Along with those...

Arend van Spriel provides a fix for a use-after-free bug in brcmfmac.

Daniel Drake avoids a hang by not trying to touch the libertas hardware
duing suspend if it is already powered-down.

Felix Fietkau provides a batch of ath9k fixes that adress some
potential problems with power settings, as well as a fix to avoid a
potential interrupt storm.

Gertjan van Wingerde provides a register-width fix for rt2x00, and
a rt2x00 fix to prevent incorrectly detecting the rfkill status.
He also provides a device ID patch.

Hante Meuleman gives us three brcmfmac fixes, one that properly
initializes a command structure, one that fixes a race condition that
could lose usb requests, and one that removes some log spam.

Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some
specific devices.

Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to
using timers that aren't allocated when 2 wire bluetooth coexistence
hardware is in use.

Sergei Poselenov changes rt2800usb to do some validity checking for
received packets, avoiding crashes on an ARM Soc.

Stone Piao gives us an mwifiex fix for an incorrectly set skb length
value for a command buffer.

All of these are localized to their specific drivers, and relatively
small.  The power-related patches from Felix are bigger than I would
like, but I merged them in consideration of their isolation to ath9k
and the sensitive nature of power settings in wireless devices.

This patch fixes a bug found by Nish Aravamudan
(https://lkml.org/lkml/2012/5/15/220) where the driver is not following
the spec (it is not aligning the rx buffer on a 16-byte boundary) and the
hypervisor aborts the registration, making the device unusable.

The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461)
to replace the kmalloc+map for a single call to dma_alloc_coherent()
because that function always aligns to a 16-byte boundary.

The stable trees will run into this bug whenever the rx buffer kmalloc call
returns something not aligned on a 16-byte boundary.

However, the suspend handler currently tries to send host sleep commands
