Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
pull request: wireless-next 2014-05-02
Please pull this batch of updates intended for the 3.16 stream...
For the mac80211 bits, Johannes says:
"In this round we have a large number of small features and
improvements from people too numerous to list here. The only really
bit thing is Michał and Luca's CSA work (including changing how
interface combination verification is done)."
For the Bluetooth bits, Gustavo says:
"Here goes some patches for the -next release. There is nothing
really special for this pull request, just a bunch of refactors,
fixes and clean ups."
For the ath10k/ath6kl bits, Kalle says:
"For ath6kl Kalle fixed a bunch of checkpatch warnings.
In ath10k we had more changes, major ones being:
* fix memory allocation failures after a firmware crash (Michal)
* some rework of DFS configuration to enable it correctly in all cases
(Michal)
* add a new firmware crash option to make it possible to crash 10.1
firmware for testing purposes (Marek P)
* fix RTS/CTS protection in certain cases (Marek K)
* fix wrong RSSI and rate reporting in some cases (Janusz)
* fix firmware stats reporting (Chun, Ben & Bartosz)"
For the iwlwifi bits, Emmanuel says:
"I have here a bunch of unrelated things. I disabled support for
-7.ucode which means that I can removed a lot of code. Eliad has
a brand new feature: we reduce the Tx power when the link allows -
this reduces our power consumption. The regular changes in power and
scan area. One interesting thing though is the patches from Johannes,
we have now GRO which allows to increase our throughput in TCP Rx. The
main advantage is that it reduces the number of TCP Acks - these TCP
Acks are completely useless when we are using A-MPDU since the first
packet of the A-MPDU generates a TCP Ack which is made obsolete by
the next packets."
Along with that, there are a variety of updates to b43, mwifiex,
rtl8180 and wil6210 drivers and a handful of other updates here
and there.
Please let me know if there are problems!
