====================
pull request: wireless-next 2014-01-01
These patches were tucked-in with me for my long winter's nap!
Please pull them for the 3.14 stream...
For the mac80211 bits, Johannes says:
"Here I just have a collection of fixes/improvements/cleanups, very
little really stands out apart from CSA fixes, vendor command support
and the RCU speedups."
For the iwlwifi bits, Emmanuel says:
"I have hear quite a few things. Alex continues his work on power
management. Arik is reworking the transport API by unifying redudant
APIs and making error handling more generic. Eyal keeps on digging in
the rate scaling code.
We also have two new features - Max is using the brand new generic
cipher infrastructure in mac80211, and Lilach implements the smart fifo
which allows to save power by making interrupt coalescing smarter."
Along with those, Arend and company bring a batch of brcmfmac.
Sujith and Felix bring the usual high level of ath9k activity as well.
Bing gives mwifiex some love as well, and a handful of other bits
get updates here and there.
