Ideally, it wouldn't be affected by running a sniffer, so I think best would be to increment NOPORTS when someone has joined the group on the interface and IGNOREDMULTI when nobody has, but I'm not sure it's worth the trouble to check. So I'm good with that, or IGNOREDMULTI all the time. +-DLS -- 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
