I did skim through the code and found iface_set_mac->netdev_set_etheraddr->netdev->netdev_class->set_etheraddr-> For DPDK netdev netdev_dpdk_set_etheraddr Though the code in 2.13 is different from the patch. I assumed support is there and I was not setting it the right way. To answer your question why I need to change mac address, we recently moved from kernel/bond to ovs-dpdk/bond with 2 members. With kernel/bond, all 3 interfaces (bond + 2 members) had same mac address and if one member goes down traffic was not hit. With ovs/dpdk bond, bridge and active-slave share the same mac address. When active-slave link goes down traffic takes 60seconds hit. Kernel/bond has bond_mode=4 and ovs/dpdk has balance-tcp configured.
