Yeah, I think it's best to handle the mesh WEXT ioctls separately for
now.  There are really only 4 of them (get/set SSID, set channel, get
mode) that matter for mesh.  The rest of the ioctls that the mesh
interface supports get redirected to the cfg80211 handlers because they
aren't specific to mesh.
