Pierre Riteau ee63b3253d Fix MTU of NetworkManager bridge VLAN interfaces
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.
