Hi Sven,

seems to work as expected now:

# ethtool -S eth2 |grep rxq
    rxq_0_desc_enqueue: 983
    rxq_0_queue_full_drops: 0
    rxq_0_packets_early_drops: 0
    rxq_0_packets_bm_drops: 0
    rxq_1_desc_enqueue: 14
    rxq_1_queue_full_drops: 0
    rxq_1_packets_early_drops: 0
    rxq_1_packets_bm_drops: 0
    rxq_2_desc_enqueue: 12
    rxq_2_queue_full_drops: 0
    rxq_2_packets_early_drops: 0
    rxq_2_packets_bm_drops: 0
    rxq_3_desc_enqueue: 4
    rxq_3_queue_full_drops: 0
    rxq_3_packets_early_drops: 0
    rxq_3_packets_bm_drops: 0
