The get_isr function combines the AR_ISR_TXOK ,AR_ISR_TXERR , AR_ISR_TXEOL and AR_ISR_TXDESC interrupts as a ATH9K_INT_TX mask. so I cannot get the actual interrupts from the get_isr function.
I tried to destinguish the interrupts AR_ISR_TXOK ,AR_ISR_TXERR , AR_ISR_TXEOL and AR_ISR_TXDESC. I've tried to read the AR_ISR_S0 and AR_ISR_S1 registers, and found that the AR_ISR_TXOK interrupt always appears togerther with the AR_ISR_TXDESC interrupt, though the AR_IMR,AR_IMR_S0 and AR_IMR_S1 interrupt related bits are set. I have no idea how to distinguish the time when the frame is being transmitted(AR_ISR_TXDESC interrupt theoretically) and when the frame is acked (AR_ISR_TXOK interrupt theoretically). I just want to measure the time delay between such two events.
So, How can i distinguish TXOK and TXDESC interupts?
