I haven't seen any updated on this and now that I tested this with the
current kernel, I'm seeing a failure as well (though, a different one):

nl80211: mesh join (ifindex=3)
  * freq=5260
  * vht_enabled=0
  * ht_enabled=1
  * sec_channel_offset=0
  * channel_type=1
  * Mesh ID (SSID) - hexdump_ascii(len=14):
 6d 65 73 68 2d 6f 70 65 6e         wpas-mesh-open  
  * flags=00000001
nl80211: mesh join failed: ret=-22 (Invalid argument)


I had left this patch set in my queue, but I'm dropping it now due to
the identified issues here and no obvious resolution for them. If you
have an updated version that works with the current Linux kernel, please
send an updated set.
