ath9k: add duration field to ath_tx_status
Add duration field to ath_tx_status in order to report frame duration for each entry in multi-retry chain. These fields will be used in ACK timeout estimation algorithm (dynack) Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
