Title:
networkd sometimes doesn't set mtu received by dhcp
Status in systemd package in Ubuntu:
Confirmed
Bug description:
I'm running ubuntu-minimal-1910-eoan on google compute engine with systemd
242-7ubuntu3.7.
GCE has mtu 1460, set by dhcp. After having networking issues, I figured out
that the mtu on the interface was sometimes incorrectly set to 1500.
I manually changed it to 1420 to have a working system again and enabled
debugging for systemd-networkd.

On dhcp renew (09:51:00), mtu got properly changed to 1460.
On next dhcp renew (21:50:59) it got changed back to previous value 1420.
In all cases, /run/systemd/netif/leases/2 correctly contained MTU=1460.
There have been some changes to mtu handling in the past, I assume
this is a regression, potentially from
https://github.com/systemd/systemd/issues/12552 or
https://github.com/systemd/systemd/issues/6593.
