You can also use mii-tool (stock with libranet)
I noticed the network was DAMN slow with 10BaseT-FD/HD
But changing back to 100BaseTx-FD just hangs the network
after setting to 100BaseT-FD (mii-tool -F 100BaseTx-FD)
Try to auto negotiate (mii-tool -r)
#mii-tool -v
eth0: negotiated 100baseTx-FD, link ok
