Some changes can now be made to interfaces without restarting. Changes to
routes, IP addresses, netmask, or MTU will now be applied using iproute2
without restarting the interface, and the ifcfg file will be updated.

Since this change uses iproute2 to make changes to live interfaces, it
does not allow MTU on DPDK interfaces to be modified in place. DPDK
requires that ovs-vsctl be run to modify MTU. For DPDK interfaces, MTU
changes will result in an interface restart.
