However, this function currently does not free cfg80211 sme. This results in hanging connection attempts in some cases e.g. when mac80211 authentication attempt is denied, we have this function call: ieee80211_rx_mgmt_auth() -> cfg80211_rx_mlme_mgmt() -> cfg80211_process_auth() -> cfg80211_sme_rx_auth() -> __cfg80211_connect_result() but cfg80211_sme_free() is never get called.
