IPアドレスが割り当てられていないすべてのインターフェイスに対してこの操作を繰り返します。
私の考えでは、これがdhcpに関連しているようです。どのインターフェイスでもDHCPクライアントを実行したくありません。これらのインターフェイスの一部には固定アドレスがあり、他のインターフェイスにはありません。インターフェイスのIPアドレスがないようです。 NetworkManager はデフォルトで自動設定を使用し、DHCP を取得しようとします。リンクローカルを割り当てるとAPIPAアドレスを取得しますが、それも望ましくありません。
IPアドレスなしで1つのインターフェイスのみを有効にできますか？ NetworkManagerにIPを取得しようとしないようにしますか？
