記述のethtoolというLINX コマンドを打つ。
※気をつけないと色々設定できてしまうLINX コマンドなんで
注意が必要
#ethtool -i eth0
オプションiでNICのドライバのバージョンを表示できる
eth0はeth1ならeth1を設定。
家だと
[root@localhost sbin]# /sbin/ethtool -i eth0
driver: e1000
version: 7.3.21-k4-2-NAPI
firmware-version: N/A
bus-info: 0000:00:03.0
[root@localhost sbin]#
と出た。
えーと、REALTECなんですが。
7.3.21-k4-2-NAPIで検索すると

てか仮想NIC失敗とかｗファイルシステムだし所詮。。
あとp指定番号のポートが点等する
# /sbin/ethtool -p eth0
て、仮想だから点等するわけねぇｗ
でも使えそう。。
/sbin/ethtool -S eth0
大文字S
状態やね

なんだかんだドライバ、ファームウェアバージョンのiもつかえると思う
[root@localhost sbin]# /sbin/ethtool -i eth0
driver: e1000
version: 7.3.21-k4-2-NAPI
firmware-version: N/A
bus-info: 0000:00:03.0
でも基本はオプションなしの内容、これ結線状態までわかるのが
すげえ
