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.
====================
