I'm presenting here one counter suggested by the standard, and one counter defined by the NXP ENETC controller from LS1028A. Both counters are reported globally and per traffic class - drivers get different callbacks for reporting both of these, and get to choose what to report in both cases. The iproute2 counterpart is available here for testing: https://github.com/vladimiroltean/iproute2/commits/taprio-xstats Vladimir Oltean (5): net/sched: taprio: don't overwrite "sch" variable in taprio_dump_class_stats() net/sched: taprio: replace tc_taprio_qopt_offload :: enable with a "cmd" enum net/sched: taprio: add netlink reporting for offload statistics counters net: enetc: refactor enetc_setup_tc_taprio() to have a switch/case for cmd net: enetc: report statistics counters for taprio drivers/net/dsa/hirschmann/hellcreek.c | 14 ++- drivers/net/dsa/ocelot/felix_vsc9959.c | 4 +- drivers/net/dsa/sja1105/sja1105_tas.c | 7 +- .../net/ethernet/engleder/tsnep_selftests.c | 12 +- drivers/net/ethernet/engleder/tsnep_tc.c | 4 +- drivers/net/ethernet/freescale/enetc/enetc.c | 3 +- drivers/net/ethernet/freescale/enetc/enetc.h | 1 + .../net/ethernet/freescale/enetc/enetc_qos.c | 110 ++++++++++++++---- drivers/net/ethernet/intel/igc/igc_main.c | 13 ++- .../ethernet/microchip/lan966x/lan966x_tc.c | 10 +- .../net/ethernet/stmicro/stmmac/stmmac_tc.c | 7 +- drivers/net/ethernet/ti/am65-cpsw-qos.c | 11 +- include/net/pkt_sched.h | 56 +++++++-- include/uapi/linux/pkt_sched.h | 10 ++ net/sched/sch_taprio.c | 90 ++++++++++++-- 15 files changed, 286 insertions(+), 66 deletions(-) -- 2.34.1
