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
====================
