Is the list of people who agreed longer than "Reviewed by" list? H> Are you seeing something broken as of this patch? As I already explained, first, we are dropping absolutely legitimate packets. At the time of arrival there were nothing wrong about them. This is idelogically wrong from viewpoint of abstract network stack. Second, the problem should be fixed in a different way: when we put packets on the queue, we should take all important values out of the ifnet and store them on queue entry. -- Gleb Smirnoff
