Johannes Berg says:

====================
We have a fair number of patches, but many of them are from the
first bullet here:
 * EAPoL-over-nl80211 from Denis - this will let us fix
   some long-standing issues with bridging, races with
   encryption and more
 * DFS offload support from the qtnfmac folks
 * regulatory database changes for the new ETSI adaptivity
   requirements
 * various other fixes and small enhancements
====================
