Merge tag 'mac80211-next-for-davem-2017-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
Another set of patches for -next:
 * API support for concurrent scheduled scan requests
 * API changes for roaming reporting
 * BSS max idle support in mac80211
 * API changes for TX status reporting in mac80211
 * API changes for RX rate reporting in mac80211
 * rewrite monitor logic to prepare for BPF filters
 * bugfix for rare devices without 2.4 GHz support
 * a bugfix for recent DFS changes
 * some further cleanups

The API changes are actually at a nice time, since it's
typically quiet just before the merge window, and trees
can be synchronized easily during it.
