[Armadillo:04251] Armadillo-500のネットワーク設定について(ethtool使用)

[大木朋春]

大木と申します。
いつもお世話になっております。

Armadillo-500（2.6.18-at8使用）においてethtoolを使ってネットワーク設定を行った場合、以下の
ような現象が出ております。
ethtoolは、debianのサイトからarmバイナリをダウンロードして使用しています。

＜現象＞
ethtoolで10M half／full、100M half／fullの設定を行っても、LANケーブル挿抜時の表示が全て

 eth0: link up, 100Mbps, full-duplex, lpa 0x05E1

となり、100M fullと表示される。
ただし、ethtool eth0でステータス表示をすると、設定した通りの設定値が表示される。


おそらくドライバ側の問題かと思いますが、対処可能であれば対処内容をご教示ください。

# LANケーブル抜いた状態でethtool eth0をやっても常に
# Link detected: yes
# となるのは、また別の問題。

以下、その時のログです。
