The use of rte_strerror(-error) in netdev_dpdk_set_qos() looks a little
confusing to me. Is ->qos_construct() supposed to return a negative
number for errors? But that doesn't seem to mesh with the assignment
"error = EOPNOTSUPP;" earlier in netdev_dpdk_set_qos(). But maybe I'm
not familiar enough with how DPDK reports errors.
