Merge tag 'mac80211-next-for-davem-2016-06-09' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
For the next cycle, we have the following:
 * the biggest change is Michał's work on integrating FQ/codel
   with the mac80211 internal software queues
 * cfg80211 connect result gets clarified for the
   "no connection at all" case
 * advertisement of per-interface type capabilities, in case
   they differ (which makes a lot of sense for some capabilities)
 * most of the nl80211 & hwsim unprivileged namespace operation
   changes
 * human-readable VHT capabilities in debugfs
 * some other cleanups, like spelling
====================
