   3 Subject: [PATCH] mac80211: fix setting IEEE80211_KEY_FLAG_RX_MGMT for AP mode
   4  keys
   5
   6 key->sta is only valid after ieee80211_key_link, which is called later
   7 in this function. Because of that, the IEEE80211_KEY_FLAG_RX_MGMT is
   8 never set when management frame protection is enabled.
