thanks you reply!
maybe you don't understand this problem. Sorry, my English is so poor!
I mean:
the normal device can display infomation with mii-tool command,like:
# mii-tool
eth0: negotiated 1000baseT-FD flow-control, link ok
eth1: negotiated 1000baseT-FD flow-control, link ok
eth2: negotiated 1000baseT-FD flow-control, link ok
eth3: negotiated 1000baseT-FD flow-control, link ok
if somewhere had errors after, it's will be can't display information with mii-tool command, and have ' no MII interfaces found ', like:
note: this errors, Can only reinstall the system will repair.
I wonder, if don't reinstall the new system, can I fix this problem, how to?
