[RFC][PATCH 2/2] ath9k: use also AR_DecryptBusyErr to determine decrypt errors

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

 



Prevent non-decrypted frames with DecryptBusyErr flag set to be marked
decrypted.

Have seen such a frame with status 0x40030bc1 (due to bit error?).
