Subject: ath9k state machine ?


Hello linux-wireless colleagues,

Let me disturb you with a non-deep-in-the-code question...
I am working on an specific application starting from ath9k driver.
Basically I have to capture acks being used as triggers for other
actions at user level, so it would be useful to know the "journey of a
packet" through the driver (ath9k). Is this information available to
you? (publicly available?) I have searched for a while without results;
at the moment I am "blindly" working with a code analyzer through the
driver source with little and slow results, but A description of the
"state machine" would be more than useful; do you now where can I get
something?

Thank you in advance for your help
Guido

pls start from ath9k_tx in main.c and the interrupt path in
ath_tx_tasklet/ath_tx_edma_tasklet
