Merge tag 'mac80211-next-for-davem-2016-04-13' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next into master
To synchronize with Kalle, here's just a big change that affects
all drivers - removing the duplicated enum ieee80211_band and
replacing it by enum nl80211_band. On top of that, just a small
documentation update.
