They didn't find any because there is no need to disable it. I hardly think that the network stack should fix things that Xen got wrong. Setting dev_addr to -1 is just plain wrong, other virtual ethernet devices call random_ether_addr(), it's not a new problem at all. - 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
