I use wpa_supplicant to handle 802.1X EAP-TLS authentication on wired
networks. Though it works perfectly at boot time, wpa_supplicant does
not reauthenticate after a brief network interruption e.g. an unplug
and reconnect of the network cable or a reboot of the network switch,
causing the network switch to block the port.

Is there some configuration option for wpa_supplicant to reauthenticate?

My solution (for now) is to add a "watcher" script, started as a systemd
service, to do "wpa_cli reassociate" whenever the state of the network
cable changes.

Maybe the reason is missing netlink code:
