I don't think that the patch is in the right direction. The problem comes from historical behavior that assigning an address is implicit UP. For a modern networking equipment it is a normal administrative situation that sysadmin wants to assign an address or an alias and at the same time don't implicitly bring the interface up. The problem get worse when you add CARP into the mix. For the sake of historical behavior preservation, I would prefer to see hacks to ifconfig(8) rather than to in_control(). Ifconfig could issue SIOCSIFFLAGS after SIOCAIFADDR for the sake of compatibility. In the projects/ifnet branch this all is somewhat resolved. The only place that writes IFF_UP is if_up() and drivers aren't allowed to do that. The if_init method disappears and logic of initing and assigning address is split. You may look into that branch.
