odhcp6c: add option to ignore Server Unicast option #57

Closed koalatux closed 6 years ago

My ISP has a problem and odhcp6c never gets a reply to renew messages, if sent to the server's unicast address, so I added this option as a workaround to ignore the Unicast Server Option. With that all renew messages are sent to the multicast address.

The problem is further discussed here: https://forum.turris.cz/t/turris-os-3-10-dhcpv6-loses-address-after-1-hour/7391

I can send you pcap files if you want.

Cheers, Adi
