One idea is to change arp_solicit() such that it can be invoked in this context, or provide a new helper function which will do the source address selection rules of 'arp_announce' and then invoke arp_send() as appropriate for us. - 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
