[root@cloud ~]# mii-tool -v eth0
eth0: negotiated 100baseTx-FD flow-control, link ok
product info: vendor 00:00:20, model 32 rev 1
basic mode: autonegotiation enabled
basic status: autonegotiation complete, link ok
capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD

link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
从上面可以看出eth0 工作 100M全双工自适应模式下
