Subject: [PATCH] ath10k: fix tx status flag setting for management frames
Git-commit: 058a7eab9d9ee12f57282eb0b606668dada70d7a
Patch-mainline: v4.20-rc1
References: FATE#326294

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
