OK, sounds good. By the way, I think you can probably hit it more often if you have something on the virtual network sending lots of multicast traffic while you're creating the interface. That'll increase the odds that you'll get into ip_check_mc() with a partially initialized in_dev.
You can use "ping -I intfX 224.0.0.1" (e.g.) to generate multicast traffic, though you'd want more than one. :-) +-DLS - 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
