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 ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
