From 3c3769e63301fd92fcaf51870c371583dd0282ce Mon Sep 17 00:00:00 2001 From: Linus Lüssing Date: Wed, 4 Sep 2013 02:13:39 +0200 Subject: bridge: apply multicast snooping to IPv6 link-local, too MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The multicast snooping code should have matured enough to be safely applicable to IPv6 link-local multicast addresses (excluding the link-local all nodes address, ff02::1), too.
