Subject: inet6: Only log RA's when they are from a new server
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=985ee29b5ad3825dfb922f6cf572a72fbe816256;p=thirdparty%2Fdhcpcd.git

inet6: Only log RA's when they are from a new server

We cannot log them normally as there are implementations which
vary the expiry times based on their own times so each message is
different. As such, we only log from new servers or coming back
from expiration.
