After upgrade to 25.7, in log these warnings start to appear.
Did I miss any change?
Skipping AdvLinkMTU configuration since it cannot be applied on opt3
Skipping AdvLinkMTU configuration since it cannot be applied on opt5
Skipping AdvLinkMTU configuration since it cannot be applied on opt8
All are VLAN interfaces.
It simply means the MTU to be set is larger than the MTU already enforced, which doesn't work.
