Hello,
your patch helps, partially:

- I've had a disconnection after a few minutes:
Michael MIC failure wireless event: keyix=0 src_addr=00:1a:70:47:cc:5c
Michael MIC failure detected
WPA: Sending EAPOL-Key Request (error=1 pairwise=1 ptk_set=1 len=99)
TKIP countermeasures started
wpa_driver_bsd_set_countermeasures: enabled=1
State: COMPLETED -> DISCONNECTED
wpa_driver_bsd_deauthenticate
wpa_driver_bsd_del_key: keyidx=0
wpa_driver_bsd_del_key: keyidx=1
wpa_driver_bsd_del_key: keyidx=2
wpa_driver_bsd_del_key: keyidx=3
wpa_driver_bsd_del_key: addr=00:1a:70:47:cc:5c keyidx=0
ioctl[SIOCS80211, op 20, len 7]: Can't assign requested address
EAPOL: External notification - portEnabled=0
EAPOL: SUPP_PAE entering state DISCONNECTED
EAPOL: SUPP_BE entering state INITIALIZE
EAPOL: External notification - portValid=0
Added BSSID 00:1a:70:47:cc:5c into blacklist
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

- I've been able to reconnect without kld-reloading the module, by
killing and restarting wpa_supplicant
