Operating IGMP snooping on a port that is blocking communication disables the
inter-port relay blocking for IGMP frames, so that these frames are forwarded.
Operating MLD snooping on a port that is blocking communication disables
inter-port relay blocking for MLD frames, so that these frames are forwarded.
Operating GSRP on a port that is blocking communication disables inter-port
relay blocking for GSRP aware frames, so that these frames are forwarded.
Operating CFM on a port that is blocking communication disables inter-port
relay blocking for CFM frames, so that these frames are forwarded.
