Subject: [PATCH V2 1/2] wifi: ath11k: fix tx status reporting in encap offload mode
Date: Fri, 31 Mar 2023 19:49:31 -0700 [thread overview]
Message-ID: <20230401024932.11722-2-quic_pradeepc@quicinc.com> (raw)
In-Reply-To: <20230401024932.11722-1-quic_pradeepc@quicinc.com>
ieee80211_tx_status() treats packets in 802.11 frame format and
tries to extract sta address from packet header. When tx encap
offload is enabled, this becomes invalid operation. Hence, switch
to using ieee80211_tx_status_ext() after filling in station
address for handling both 802.11 and 802.3 frames.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
