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