+          Normally, a multicast router runs a userspace daemon and decides
+          what to do with a multicast packet based on the source and
+          destination addresses. If you say Y here, the multicast router
+          will also be able to take interfaces and packet marks into
+          account and run multiple instances of userspace daemons
+          simultaneously, each one handling a single table.
