Subject: [PATCH] mac80211: Fix bug in Tx ack status reporting in 802.3 xmit path
Date: Wed, 22 Jul 2020 19:50:17 +0530	[thread overview]
Message-ID: <1595427617-1713-1-git-send-email-vthiagar@codeaurora.org> (raw)

Allocated ack_frame id from local->ack_status_frames is not really
stored in the tx_info for 802.3 Tx path. Due to this, tx ack status
is not reported and ack_frame id is not freed for the buffers requiring
tx ack status. Also move the memset to 0 of tx_info before
IEEE80211_TX_CTL_REQ_TX_STATUS flag assignment.

Fixes: 50ff477a8639 ("mac80211: add 802.11 encapsulation offloading support")
