We are seeing an issue on Rocky Linux 9 where VLAN interfaces on bridges have their MTU set to MTU-1 after rebooting. This is likely related to how MTU is set by NetworkManager for bridges: it first sets the MTU to MTU-1 before setting it to the correct value [1]. We can work around this issue by not explicitly setting the MTU configuration on the VLAN interface if it is the same as the parent bridge. It will be automatically inherited from the parent.
