Merge tag 'mac80211-next-for-davem-2015-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
Lots of updates for net-next; along with the usual flurry
of small fixes, cleanups and internal features we have:
 * VHT support for TDLS and IBSS (conditional on drivers though)
 * first TX performance improvements (the biggest will come later)
 * many suspend/resume (race) fixes
 * name_assign_type support from Tom Gundersen
====================
