-Subject: [PATCH] ath9k: check for deaf rx path state
-
-Various chips occasionally run into a state where the tx path still
-appears to be working normally, but the rx path is deaf.
-
-There is no known register signature to check for this state explicitly,
-so use the lack of rx interrupts as an indicator.
-
-This detection is prone to false positives, since a device could also
-simply be in an environment where there are no frames on the air.
-However, in this case doing a reset should be harmless since it's
-obviously not interrupting any real activity. To avoid confusion, call
-the reset counters in this case "Rx path inactive" instead of something
-like "Rx path deaf", since it may not be an indication of a real
-hardware failure.
