[PATCH iproute2 v2 09/21] iplink: bridge: add support for IFLA_BR_MCAST_QUERY_USE_IFADDR

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <niko...@cumulusnetworks.com>

This patch implements support for the IFLA_BR_MCAST_QUERY_USE_IFADDR
attribute in iproute2 so it can toggle the multicast_query_use_ifaddr val.
