Current Linux kernel versions seem to follow this requirement > and ignore our bogus MLD queries. > > With this commit a link local address from the bridge interface is being > used to issue the MLD query, resulting in other Linux devices which are > multicast listeners in the network to respond with a MLD response (which > was not the case before). > > Signed-off-by: Linus Lüssing <linus.luessing@....de> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
