Karl Palsson ae57675bba odhcpd: don't enable server mode on non-static lan port
Instead of blindly enabling the odhcpd v6 server and RA server on the
lan port, only do that if the lan port protocol is "static"

This prevents the unhelpful case of a device being a dhcpv4 client and
v6 server on the same ethernet port.
