Subject: [PATCH net-next 14/15] net: bridge: mcast: improve v3 query processing
Date: Mon, 31 Aug 2020 18:08:44 +0300	[thread overview]
Message-ID: <20200831150845.1062447-15-nikolay@cumulusnetworks.com> (raw)
In-Reply-To: <20200831150845.1062447-1-nikolay@cumulusnetworks.com>

When an IGMPv3 query is received and we're operating in v3 mode then we
need to avoid updating group timers if the suppress flag is set. Also we
should update only timers for groups in exclude mode.
