driver - EtherType 0x88A4 (EtherCat) 使用時の WriteFile 関数 (NDIS) でのエラー 87

Question

C で、NDIS ドライバーのprottest.c サンプルコードを使用して、レイヤー 2 経由で Raw イーサネットフレームを送信しようとしています。必要な構造と情報がない場合、Writefile 関数は常にエラー 87 (パラメーターが正しくありません) を返します。

TCP/IP スタックなしで Raw のレイヤ 2 でこの関数を使用して書き込むことはできません。何が問題なのですか?

ご協力いただきありがとうございます。よろしくお願いします。
