Haswell vlan対応 / 2022-11-19 (土)

Ubuntu 22.04 JammyへのUpdateでmacvlanに振ったIPアドレスが効いてなさそうな件。

取り敢えず、VMゲストとの通信よりも、4月に開通した「楽天ひかり」側のセグメントにも足を生やす方がメリットが大きいので、gt110bに倣ってVLAN対応することに。

yano@haswell:/etc/netplan$ cat 25-enp0s25-config.yaml

            dhcp4: no
            dhcp6: no
            mtu: 8996

    version: 2
