using kernel 2.3.47, with either ifconfig or ip, once an interface has been
marked 'down', it can not be brought up again. requested action brings:
router:~# ip l s eth2 up
router:~# ip l s eth2 down
router:~# ip l s eth2 up
SIOCSIFFLAGS: No such device
router:~# ip l s eth2 mtu 1476
SIOCSIFMTU: No such device
router:~# ip a a 127.0.0.2 brd + dev eth2
router:~# ip a s eth2
8: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:80:c8:1d:37:fc brd ff:ff:ff:ff:ff:ff
inet 127.0.0.2/32 scope global eth2
router:~# ip a f eth2
router:~# ip a s eth2
8: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:80:c8:1d:37:fc brd ff:ff:ff:ff:ff:ff
from this point on, addresses can be added or removed but most flags or
options can not change.
