Description of problem:
In a bare-metal cluster with ipvlan over vlan over bond interfaces, the mtu value defined for an ipvlan interface in a network-attachment-definitions is not properly applied to the pod after a cluster restart.
Version-Release number of selected component (if applicable):
OpenShift 4.14.22
How reproducible:
After a reboot of all the cluster worker nodes, like after an upgrade or applying a MachineConfig that triggers a reboot.
Steps to Reproduce:
1. Configure a bond interface
2. Configure a vlan interface over the bond (with a MTU value of 9126)
3. Configure via a NetworkAttachmentDefinition an ipvlan over the vlan interface with a specific mtu (set to 1500)
4. Reboot all the worker nodes
5. Check the mtu set for the ipvlan interface from the pod
Actual results:
MTU value defined for the master interface.
Expected results:
MTU value defined in the NetworkAttachmentDefinition
Additional info:
After some time, deleting the pod will recreate it with the correct MTU value.
