From: Nikolay Aleksandrov <nikolay@nvidia.com>

Add control and dump support for the global mcast_query_interval
option which controls the interval between queries sent by the bridge
after the end of the startup phase. To be consistent with the same
bridge-wide option the value is reported with USER_HZ granularity and
the same granularity is expected when setting it.
Syntax:
 $ bridge vlan global set dev bridge vid 1 mcast_query_interval 13000
