Thanks for the quick review. Yes, as the next step, we would need
ethtool rx-nfc API to allow Rx flow configuration to various Rx
queues. Also, Rx priority queues are still off by default:

[GENET_V3] = {
        .tx_queues = 4,
        .tx_bds_per_q = 32,
        .rx_queues = 0,
        .rx_bds_per_q = 0,

[GENET_V4] = {
        .tx_queues = 4,
        .tx_bds_per_q = 32,
        .rx_queues = 0,
        .rx_bds_per_q = 0,
