In future, users can avail it to add more per-queue specific counters. Number of rx/tx queues displayed is depending on the available rx/tx queues in that particular MAC config and this number is limited up to the MTL_MAX_{RX|TX}_QUEUES defined in the driver. Ethtool per-queue statistic display will look like below, when users start adding more counters. Example - 1: q0_tx_statA: q0_tx_statB: q0_tx_statC: | q0_tx_statX: . . . qMAX_tx_statA: qMAX_tx_statB: qMAX_tx_statC: | qMAX_tx_statX: q0_rx_statA: q0_rx_statB: q0_rx_statC: | q0_rx_statX: . . . qMAX_rx_statA: qMAX_rx_statB: qMAX_rx_statC: | qMAX_rx_statX: Example - 2: Ping test using the tx queue 3. $ tc qdisc add dev enp0s30f4 root mqprio num_tc 2 map 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 queues 3@0 1@3 hw 0 Statistic before ping: --------------------- $ ethtool -S enp0s30f4 [ snip ] q3_tx_pkt_n: 7916 q3_tx_irq_n: 316 [ snip ] $ cat /proc/interrupts [ snip ] 143: 0 0 0 316 0 0 0 0 IR-PCI-MSI 499719-edge enp0s30f4:tx-3 [ snip ] $ ping -I enp0s30f4 192.168.1.10 -i 0.01 -c 100 > /dev/null Statistic after ping: --------------------- $ ethtool -S enp0s30f4 [ snip ] q3_tx_pkt_n: 8016 q3_tx_irq_n: 320 [ snip ] $ cat /proc/interrupts [ snip ] 143: 0 0 0 320 0 0 0 0 IR-PCI-MSI 499719-edge enp0s30f4:tx-3 [ snip ] Vijayakannan Ayyathurai (2): net: stmmac: add ethtool per-queue statistic framework net: stmmac: add ethtool per-queue irq statistic support Voon Weifeng (1): net: stmmac: fix INTR TBU status affecting irq count statistic drivers/net/ethernet/stmicro/stmmac/common.h | 13 ++++ .../net/ethernet/stmicro/stmmac/dwmac4_lib.c | 7 +- .../ethernet/stmicro/stmmac/stmmac_ethtool.c | 67 ++++++++++++++++++- .../net/ethernet/stmicro/stmmac/stmmac_main.c | 5 ++ 4 files changed, 89 insertions(+), 3 deletions(-) base-commit: e4637f621203cb482f3ddb590cfe9f65045d92a6 -- 2.17.1
