Recent (20190207) changes to odhcpd makee it dependent on OpenWrt
logical interfaces. Boot time race conditions may make odhcpd binding
a challenge. Intermittent or inconsistent problems can occur with DHCP
requests until odhcpd is restarted. Change start up scripts to use
procd interface triggers such as dnsmasq and others have already.
