Network Manager がデバイスの状態を使用不可に変更するのはなぜですか?

NetworkManagerとNetworkManager-nmcliがインストールされているYoctoディストリビューションでは、Wi-Fi wlan0デバイスを使用できない状態に保つことはできません。私が受け取ったエラーメッセージは次のとおりです。

device (wlan0): state change: unmanaged -> unavailable (reason 'managed', sys-iface-state: 'external')

私の質問は、どのプログラムがデバイスを管理しているかをどのように知ることができるかということです。ネットワークデバイスを生成できるすべてのsysvinitスクリプトを削除して削除しましたが、まだ同じ問題が発生します。

上記のようにNetworkManagerが起動したら、wlan0デバイスを作成してから利用できない状態に切り替えるという事実に絞り込みました。

これは私の/etc/network/interfacesです。

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

これは私の/etc/NetworkManager/NetworkManager.confです。

[main]
plugins=keyfile,ifupdown
rc-manager=symlink
dns=dnsmasq

[ifupdown]
managed=true

/usr/lib/NetworkManager/conf.d/10-globalally-management-devices.conf

[keyfile]
unmanaged-devices=*,except:type:wifi

私の（おそらく不都合な）理解では、これらすべてが大丈夫です。 wlan0がまだ「使用できません」状態である理由を理解できません。

どんな助けでも大変感謝します！ありがとう
