Is it exists option initial_state and/or
option force_link in /etc/config/network ?
need to run check WAN interface activation when it in offline state ,and updating/receiving new IP over DHCP, because currently wan interface activating/marked as active when getting new ip from external DHCP server on wan connector
or is it any other way to avoid set wan with updated IP as active by default without failover ping check routine?
