[PATCH 1/2] rt2x00: implement reconfig_complete

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



mac80211 has .reconfig_complete that can be used as indicator of
HW restart end. This will allow to configure keys/IV differently
for HW restart and normal configuration.
