29+
A userspace controlled MLD proxy implementation for a Linux bridge.
30+
The bridge itself will appear as a single multicast listening host
31+
to any MLD querier on a configured proxy port, acting in deputy
32+
for any other multicast listener behind adjacent bridge ports.
33+
This potentially reduces MLD report overhead.
34+
brmldproxy further allows to filter out specific multicast groups
35+
and bridge ports from its combined MLD report.
