# mulga-vpc-mtu — pin the VPC data NIC MTU (eth0 -> 1320) before k3s starts
# flannel, so flannel's VXLAN overlay (flannel.1 -> 1270) fits the OVN geneve
# underlay. Runs after the NICs are configured (networking + cloud-init, and
# mulga-mgmt-net for multi-NIC system VMs) and before k3s/k3s-agent. Role-
# agnostic and enabled on every node.
