Configure mtu value for DPDK port
MTU value is already written to ifcfg file if provided on the interface, but for dpdk port, we have to apply this to ovs-vsctl command via ovs_extra. This patch is adding the support to configure the given mtu vlaue to the dpdk port using ovs_extra. implements: blueprint ovs-2-6-features-dpdk Change-Id: Ic01ed8cee2edbd648de0b64dc7f01da80c153d81
