From a3300ef4bbb1f1e33ff0400e1e6cf7733d988f4f Mon Sep 17 00:00:00 2001 From: Hannes Frederic Sowa Date: Sat, 7 Dec 2013 03:33:45 +0100 Subject: ipv6: don't count addrconf generated routes against gc limit Brett Ciphery reported that new ipv6 addresses failed to get installed because the addrconf generated dsts where counted against the dst gc limit. We don't need to count those routes like we currently don't count administratively added routes. Because the max_addresses check enforces a limit on unbounded address generation first in case someone plays with router advertisments, we are still safe here.
