dhcpcd-discuss

Thanks for the quick reply.  I had wondered if that was it, and tried that
already. I just tried it again:

It looks like DHCP6 and IPV6RS don't play nice together in my config?  The
xid from the newer request6 is what is 'expected' and the xid from the
'solicit6' that it gets returned results in it being discarded?
