From: Edward Cree <ecree.xilinx@gmail.com> EF100 hardware supports attaching counters to action-sets in the MAE. Use these counters to implement stats for TC flower offload. The counters are delivered to the host over a special hardware RX queue which should only ever receive counter update messages, not 'real' network packets. Changed in v2: * added new patch #1 to fix shift UB on 32 bit (kernel test robot) Edward Cree (12): sfc: fix ef100 RX prefix macro sfc: add ability for an RXQ to grant credits on refill sfc: add start and stop methods to channels sfc: add ability for extra channels to receive raw RX buffers sfc: add ef100 MAE counter support functions sfc: add extra RX channel to receive MAE counter updates on ef100 sfc: add hashtables for MAE counters and counter ID mappings sfc: add functions to allocate/free MAE counters sfc: accumulate MAE counter values from update packets sfc: attach an MAE counter to TC actions that need it sfc: validate MAE action order sfc: implement counters readout to TC stats drivers/net/ethernet/sfc/Makefile | 2 +- drivers/net/ethernet/sfc/ef100_rx.c | 23 +- drivers/net/ethernet/sfc/efx_channels.c | 9 +- drivers/net/ethernet/sfc/mae.c | 170 +++++- drivers/net/ethernet/sfc/mae.h | 7 + drivers/net/ethernet/sfc/mae_counter_format.h | 73 +++ drivers/net/ethernet/sfc/mcdi.h | 5 + drivers/net/ethernet/sfc/net_driver.h | 17 +- drivers/net/ethernet/sfc/rx_common.c | 3 + drivers/net/ethernet/sfc/tc.c | 122 +++++ drivers/net/ethernet/sfc/tc.h | 16 + drivers/net/ethernet/sfc/tc_counters.c | 501 ++++++++++++++++++ drivers/net/ethernet/sfc/tc_counters.h | 59 +++ 13 files changed, 998 insertions(+), 9 deletions(-) create mode 100644 drivers/net/ethernet/sfc/mae_counter_format.h create mode 100644 drivers/net/ethernet/sfc/tc_counters.c create mode 100644 drivers/net/ethernet/sfc/tc_counters.h
