Note that DPDK applications should rely on rte_eth_dev_flow_ctrl_get/set()
with fc_conf->mode = RTE_FC_NONE to achieve the same behavior in a generic
While doing so translates exactly to the above ethtool calls with mlx4 and
mlx5, other PMDs do not typically leave a kernel netdevice around for
external applications to play with.
