4.19-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rakesh Pillai <pillair@xxxxxxxxxxxxxx> [ Upstream commit 058a7eab9d9ee12f57282eb0b606668dada70d7a ] The tx_status for management frames is being filled incorrectly in the flags of skb_cb. This incorrect flag setting causes the upper layers to consider that the particular frame was not transmitted properly, leading to improper behavior. Set the IEEE80211_TX_STAT_ACK flag in the info flags of skb_cb, to indicate the successful transmission of the management frame.
