GPD WINのPlamo Linuxで内蔵無線LANが使えた

GPD WINのPlamo Linuxで内蔵無線LANが使えました。

動作確認したカーネルは4.8.13で、Ubuntuのconfigをもとに作成したものです。
GPD WINのPlamo LinuxにUbuntuのパッチを当てたカーネル

下記のサイトのパッチで作成されるbrcmfmac4356-pcie.txtを/lib/firmware/brcm以下に置き、brcmfmacモジュールを再読み込みします。

# modprobe -r brcmfmac
# modprobe brcmfmac

ちなみに、内蔵無線LANはBroadcomのBCM4356というらしいです。
