Merge branch 'for-davem' of git://git./linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
This is a batch of updates intended for 3.7. The ath9k, mwifiex,
and b43 drivers get the bulk of the commits this time, with a handful
of other driver bits thrown-in. It is mostly just minor fixes and
cleanups, etc.
Also included is a Bluetooth pull, with a lot of refactoring.
Gustavo says:
"These are the changes I queued for 3.7. There are a many
small fixes/improvements by Andre Guedes. A l2cap channel
refcounting refactor by Jaganath. Bluetooth sockets now
appears in /proc/net, by Masatake Yamato and Sachin Kamat
changes ours drivers to use devm_kzalloc()."

To address this it's assumed that if the caller specifies the ifindex for

This function has an overflow in :

tcp: ecn: dont delay ACKS after CE
While playing with CoDel and ECN marking, I discovered a
non optimal behavior of receiver of CE (Congestion Encountered)
segments.
In pathological cases, sender has reduced its cwnd to low values,
and receiver delays its ACK (by 40 ms).
While RFC 3168 6.1.3 (The TCP Receiver) doesn't explicitly recommend
to send immediate ACKS, we believe its better to not delay ACKS, because
a CE segment should give same signal than a dropped segment, and its
quite important to reduce RTT to give ECE/CWR signals as fast as
possible.
Note we already call tcp_enter_quickack_mode() from TCP_ECN_check_ce()
if we receive a retransmit, for the same reason.

If NIC gave packet1, then packet2, which happen to be from "different

2) GRO is not ECN friendly
Delivering packets out of order makes TCP stack not as fast as it could
be.

mwifiex: improve scan delay logic during Tx traffic
Earlier scan command was postponed by 20msec multiple times to give
preference to Tx traffic until we find empty wmm queue.
There is a corner case in which wmm queue becomes empty immediately
after processing the packet(before 20msec) and there may be next
packet coming after some time. In this case we should not resume scan
operation.
We will use new flag to check Tx traffic and resume scan operation
only if there is no traffic for 200msec.

mwifiex: update max_chan_per_scan correctly for SSID scan
As per recent patch "
658f37b mwifiex: scan less channels..."
less channels are scanned per scan command in associated state.
Default number of channels per scan command for normal scan are
already 4, but those are 14 for SSID specific scan operation.
This code change in this patch is required for SSID specific scan.

We do similar conversion for Tx packet header but it was missing
for Rx packet header. Without this fix, Rx packet header won't

Padding arithmetic will always work for MSDUs provided first MSDU

Since commit:
fb3c19bc9687d972b83faf366b38ac807eca8f25, adding
extra padding to AMSDU is redundant since same is being performed at
mwifiex_11n_aggregate_pkt after forming the AMSDU packet. Fixing it
