Johannes Berg says:

====================
A couple of weeks worth of updates - looks like things are quiet:
 * merged net-next back to get a patch from net that another patch
   here depends on
 * various small improvements/cleanups across the board
 * 4-way handshake offload (many thanks to Arend for shepherding that)
 * mesh CSA/DFS support in mac80211
 * the skb_put_zero() we discussed previously
====================

* handshakes during 802.1X authentication. In order to use the offload
