Something like:
/sbin/ip route del default
/sbin/ip link set eth0 down
/sbin/ip addr del 192.168.1.200/24 dev eth0
(or something similar using the ifconfig <foo>)
Or how do you define to "shutdown the network interfaces"?
I guess I am lucky that I always had rc scripts running on my system.
(native distribution on harddisk, based on http://crux.nu )

Yup, there were lots of changes, also in the PHY/MII interface.

Same over here. It's good stuff!
