Merge tag 'mac80211-next-for-davem-2016-02-26' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
Here's another round of updates for -next:
* big A-MSDU RX performance improvement (avoid linearize of paged RX)
* rfkill changes: cleanups, documentation, platform properties
* basic PBSS support in cfg80211
* MU-MIMO action frame processing support
* BlockAck reordering & duplicate detection offload support
* various cleanups & little fixes
====================
