regression failure of wpa_supplicant from 12.3-RELEASE to 12.4-RELEASE

Hi wireless@freebsd.org,
I suffered regression failure of wpa_supplicant from 12.3-RELEASE to 
12.4-RELEASE, ifconfig wlan0 | grep status    
was not showing status: associated

I made notes here:
http://www.berklix.com/~jhs/src/bsd/fixes/freebsd/src/gen/usr.sbin/wpa/regression.REL=12.4-RELEASE.diff

& now have alternate sources & binaries in place to narrow it down,
recompiling after tweaks, & Murphies Law: now for the first time
ever, 12.4-rel works too, called manualy !

Normaly I use /etc/devd/my.conf, currently a bit comented out to debug:
attach 1000 {   # Iomega & Toshiba wlan stick driver=run
        match   "device-name"   "run[0-9]+" ;
        action  "ifconfig wlan$interface create wlandev $device-name ; \
                ifconfig wlan$interface regdomain ETSI ; \
                ifconfig wlan$interface country de ; \
                ifconfig wlan$interface \
                        `grep -v '^#' /var/run/wlan_params_berklix` ; \
                ifconfig wlan$interface up ; \
                service netif start" ;
# ; \
                # wpa_supplicant -i wlan$interface \
                        # -c /etc/wpa_supplicant.conf & \
                # dhclient wlan$interface; \
                # ntpdate ntp1.t-online.de" ;
        } ;

I'm not clear what service netif start is & where it belongs, so I'm reading
https://docs.freebsd.org/en/books/handbook/advanced-networking/#network-wireless33.3.4.1.3.3.
but that's I think not germane to wpa_supplicant

Anyone else had problems with wpa_supplicant from 12.3-RELEASE to 12.4-RELEASE ?

Cheers,
