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.
