Merge tag 'mac80211-for-davem-2016-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211



Johannes Berg says:

====================
A few more bugfixes:
 * limit # of scan results stored in memory - this is a long-standing bug
   Jouni and I only noticed while discussing other things in Santa Fe
 * revert AP_LINK_PS patch that was causing issues (Felix)
 * various A-MSDU/A-MPDU fixes for TXQ code (Felix)
 * interoperability workaround for peers with broken VHT capabilities
   (Filip Matusiak)
 * add bitrate definition for a VHT MCS that's supposed to be invalid
   but gets used by some hardware anyway (Thomas Pedersen)
 * beacon timer fix in hwsim (Benjamin Beichler)
====================
