RFC 8106 Support

[nqngo22]

Hello,
I just wanted to check if there is any support or plans to support for RFC 8106 section 5.1 and 5.2. I could not find it anywhere in the odhcp6c user guide.
Currently the behavior that I'm seeing is that after the lifetime expires, odhcp does not execute the script with FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF as the RA_DNS.

Thanks
