Does setting the interface down, then up works? Like ifdown eth0; ifup
eth0. Or ip link set eth0 down; ip link set eth0 up, and verifying the
address and route are restablished (in case you are using
NetworkManager, for example).
If it doesn't, does reloading the module work? rmmod sungem; modprobe
sungem.
