bridge: mcast: add MLDv2 querier support
This patch adds basic support for MLDv2 queries, the default is MLDv1 as before. A new multicast option - multicast_mld_version, adds the ability to change it between 1 and 2 via netlink and sysfs. The MLD option is disabled if CONFIG_IPV6 is disabled. Signed-off-by:Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by:
