Subject: Re: [PATCH 2/2] bridge: Use IPv6 link-local address for multicast listener queries
Date: Tue, 22 Feb 2011 10:08:23 -0800 (PST) [thread overview]
Message-ID: <20110222.100823.189696335.davem@davemloft.net> (raw)

> Currently the bridge multicast snooping feature periodically issues

Applied.
