[impact]
vlan interface has wrong mtu, which may cause lost packets due to incorrect mtu
[test case]
configure a system using the netplan cfg similar to comment 2.
alternately, networkd config can be used, similar to:
ubuntu@lp1846232-e:/run/systemd/network$ grep . *
10-netplan-ens3.2667.netdev:[NetDev]
10-netplan-ens3.2667.netdev:Name=ens3.2667
10-netplan-ens3.2667.netdev:MTUBytes=1500
10-netplan-ens3.2667.netdev:Kind=vlan
10-netplan-ens3.2667.netdev:[VLAN]

10-netplan-ens3.2667.network:LinkLocalAddressing=ipv6
10-netplan-ens3.2667.network:Address=1.2.3.4/32
10-netplan-ens3.2667.network:ConfigureWithoutCarrier=yes
10-netplan-ens3.link:[Match]
10-netplan-ens3.link:OriginalName=ens3
10-netplan-ens3.link:[Link]
10-netplan-ens3.link:WakeOnLan=off
10-netplan-ens3.link:MTUBytes=1500
10-netplan-ens3.network:[Match]
10-netplan-ens3.network:Name=ens3
10-netplan-ens3.network:[Network]
10-netplan-ens3.network:LinkLocalAddressing=ipv6
10-netplan-ens3.network:VLAN=ens3.2667
The reboot and check the mtus:
ubuntu@lp1846232-e:~$ ip l show ens3
2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1504 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
link/ether 52:54:00:12:99:1b brd ff:ff:ff:ff:ff:ff
ubuntu@lp1846232-e:~$ ip l show ens3.2667
3: ens3.2667@ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
link/ether 52:54:00:12:99:1b brd ff:ff:ff:ff:ff:ff
The base interface should have a mtu of only 1500.
[regression potential]
As this corrects/adjusts the mtu of the interface, regressions would likely involve interface(s) being assigned incorrect mtu values, which then would lead to dropped packets and/or lowered network performance.
[other info]
disco and earlier don't have the patch that introduces this problem, and focal already has the patch that fixes this (see comment 4 for details), so this is needed only for eoan.

[impact]
vlan interface has wrong mtu, which may cause lost packets due to incorrect mtu
[test case]
configure a system using the netplan cfg similar to comment 2.
alternately, networkd config can be used, similar to:
ubuntu@lp1846232-e:/run/systemd/network$ grep . *
10-netplan-ens3.2667.netdev:[NetDev]
10-netplan-ens3.2667.netdev:Name=ens3.2667
10-netplan-ens3.2667.netdev:MTUBytes=1500
10-netplan-ens3.2667.netdev:Kind=vlan
10-netplan-ens3.2667.netdev:[VLAN]
10-netplan-ens3.2667.netdev:Id=2667

10-netplan-ens3.2667.network:Name=ens3.2667
10-netplan-ens3.2667.network:[Network]
10-netplan-ens3.2667.network:LinkLocalAddressing=ipv6
10-netplan-ens3.2667.network:Address=1.2.3.4/32
10-netplan-ens3.2667.network:ConfigureWithoutCarrier=yes
10-netplan-ens3.link:[Match]
10-netplan-ens3.link:OriginalName=ens3
10-netplan-ens3.link:[Link]
10-netplan-ens3.link:WakeOnLan=off
10-netplan-ens3.link:MTUBytes=1500
10-netplan-ens3.network:[Match]
10-netplan-ens3.network:Name=ens3
10-netplan-ens3.network:[Network]
10-netplan-ens3.network:LinkLocalAddressing=ipv6
10-netplan-ens3.network:VLAN=ens3.2667
The reboot and check the mtus:
ubuntu@lp1846232-e:~$ ip l show ens3
2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1504 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
link/ether 52:54:00:12:99:1b brd ff:ff:ff:ff:ff:ff
ubuntu@lp1846232-e:~$ ip l show ens3.2667
3: ens3.2667@ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
link/ether 52:54:00:12:99:1b brd ff:ff:ff:ff:ff:ff
The base interface should have a mtu of only 1500.
[regression potential]
As this corrects/adjusts the mtu of the interface, regressions would likely involve interface(s) being assigned incorrect mtu values, which then would lead to dropped packets and/or lowered network performance.
[other info]
disco and earlier don't have the patch that introduces this problem, and focal already has the patch that fixes this (see comment 4 for details), so this is needed only for eoan.

The reboot and check the mtus:
ubuntu@lp1846232-e:~$ ip l show ens3
2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1504 qdisc fq_codel state UP mode DEFAULT group default qlen 1000

link/ether 52:54:00:12:99:1b brd ff:ff:ff:ff:ff:ff
The base interface should have a mtu of only 1500.
[regression potential]
As this corrects/adjusts the mtu of the interface, regressions would likely involve interface(s) being assigned incorrect mtu values, which then would lead to dropped packets and/or lowered network performance.
[scope]
this is needed only for Eoan.
disco and earlier don't have the patch that introduces this problem, commit 4b151b71320bbee1549afcbad5554a40d90d63b4
focal already has the patches that fix this, commit f6fcc1c2a41eae749467de58453174296b635a69 (and the commit before it)
