No, it does not change anything in the interface setup, apart from
toggling its activity state. Normally the following sequence of
commands leaves interface in its state before the first one:
ifconfig eth0 down
ifconfig eth0 up
I'll try to implement it.
I was going to have a shot, but since you have a better idea of what
happens shoot.
