Merge tag 'mac80211-next-for-davem-2016-10-04' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
This time around, we have
* Neighbor Awareness Networking (NAN) APIs
* a fix for a previous patch that caused memory corruption
in wireless extensions key settings
* beacon rate configuration for AP and mesh
* memory limits for mac80211's internal TXQs
* a (fairly involved) fix for the TXQ vs. crypto problems
* direct cfg80211 driver API for WEP keys
This also pulls in net-next to fix the merge conflicts, see
the merge commit for more details.
