If you don't apply this patch
http://marc.info/?l=linux-wireless&m=121739858214351&w=2 to ath5k
driver, the ath5k will not send mesh beacon after wake up, and hence
they can't find each other,  but after apply this  patch the ath5k
driver will lead to crash after work a while, as far as I know Andrey
Yurovsky was working for figure it out. don't know if this problem was
fixed so far. anywhere if worth to try this patch if you want the
ath5k full support 11s.
