Subject: [PATCH] mac80211: fix setting IEEE80211_KEY_FLAG_RX_MGMT for AP mode keys
Git-commit: 211710ca74adf790b46ab3867fcce8047b573cd1
Patch-mainline: v4.19-rc7
References: bsc#1051510
key->sta is only valid after ieee80211_key_link, which is called later
in this function. Because of that, the IEEE80211_KEY_FLAG_RX_MGMT is
never set when management frame protection is enabled.
