[ 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.
Tested HW: WCN3990 Tested FW: WLAN.HL.2.0-01188-QCAHLSWMTPLZ-1
