I don't see any problem with this. If you're using IP_MULTICAST_IF with a bound socket, it forces you to use that interface, anyway.
I'm not sure multicasting works as expected in some other cases with bound sockets (looks like there may be some holes to evade the binding), but that's in old code. I don't see any problems from this patch. +-DLS Acked-by: David L Stevens <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
