ath9k: add stability fixes for long standing hang issues (FS#13, #34, #373, #383)
The radio would stop communicating completely. This issue was easiest to trigger on AR913x devices, e.g. the TP-Link TL-WR1043ND, but other hardware was occasionally affected as well. The most critical issue was a race condition in disabling/enabling IRQs between the IRQ handler and the IRQ processing tasklet Signed-off-by: Felix Fietkau <nbd@nbd.name>

+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.

+Subject: [PATCH] ath9k: fix race condition in enabling/disabling IRQs
+
+The code currently relies on refcounting to disable IRQs from within the
+IRQ handler and re-enabling them again after the tasklet has run.
+
+However, due to race conditions sometimes the IRQ handler might be
+called twice, or the tasklet may not run at all (if interrupted in the
+middle of a reset).
+
+This can cause nasty imbalances in the irq-disable refcount which will
+get the driver permanently stuck until the entire radio has been stopped
+and started again (ath_reset will not recover from this).
+
+Instead of using this fragile logic, change the code to ensure that
+running the irq handler during tasklet processing is safe, and leave the
+refcount untouched.
