I am not sure on when the hardware interrupt ATH5K_INT_TXOK would be triggered.
Previously, I programmed the driver to let it periodically send out probe requests, and it seems the transmission of probe req does not raise ATH5K_INT_TXOK. I am going to run some tests today with DATA packet transmission and see how things come out. Thanks.
