[PATCH 2/3] ath9k: make beacon timer initialization more reliable

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

 



When starting the AP beacon timer, it assumes that the TSF has recently
been cleared. Set the SC_OP_TSF_RESET flag to ensure that this is always
the case.
