my name is Vito, I would want to know if is possible to know the time of permanence of a packet in the hardware buffer.
I have seen in the file “if_ath.c” the function “ath_tx_start”, in it “ath_hal_puttxbuf” puts in hardware buffer the packet and “ath_hal_txstart” starts the transmission. I would want to be able to know how much time the packet employ in order to exit from the card, eventually putting a single package for time in hardware buffer.
I think can be used the interruptions but I do not understand like making.
Thanks for aid.
