Code Issues Pull Requests Releases Wiki Activity

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
