ath10k: fix rssi and rate reporting
RSSI and RATES fields are valid only when START_VALID bit is set. So, in current implementation we have to remember/caclulate them when START_VALID and report the same when only END_VALID is set. Currently during heavy traffic we could have: - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID ... Next using monitor interface we will see: - 10 packets with correct rssi/rates - 10 packets with rssi=-95/rate=6Mbps Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
