This is the first (small) series which exposes some stats via the corresponding ethtool interface. Here (thanks to the excitability of netlink) we expose pause frame stats via the same interfaces as ethtool -a / -A. In particular the following stats from the standard: - 30.3.4.2 aPAUSEMACCtrlFramesTransmitted - 30.3.4.3 aPAUSEMACCtrlFramesReceived 4 real drivers are converted, I believe we got confirmation from maintainers that all exposed stats match the standard. v3: - fix mlx5 build - adjust the init logic in patch 1 v2: - netdevsim: add missing static - bnxt: fix sparse warning - mlx5: address Saeed's comments Jakub Kicinski (8): ethtool: add standard pause stats docs: net: include the new ethtool pause stats in the stats doc netdevsim: add pause frame stats selftests: add a test for ethtool pause stats bnxt: add pause frame stats ixgbe: add pause frame stats mlx5: add pause frame stats mlx4: add pause frame stats Documentation/networking/ethtool-netlink.rst | 11 ++ Documentation/networking/statistics.rst | 57 ++++++++- .../net/ethernet/broadcom/bnxt/bnxt_ethtool.c | 17 +++ .../net/ethernet/intel/ixgbe/ixgbe_ethtool.c | 11 ++ .../net/ethernet/mellanox/mlx4/en_ethtool.c | 19 +++ .../net/ethernet/mellanox/mlx4/mlx4_stats.h | 12 ++ .../ethernet/mellanox/mlx5/core/en_ethtool.c | 9 ++ .../net/ethernet/mellanox/mlx5/core/en_rep.c | 9 ++ .../ethernet/mellanox/mlx5/core/en_stats.c | 29 +++++ .../ethernet/mellanox/mlx5/core/en_stats.h | 3 + drivers/net/netdevsim/Makefile | 2 +- drivers/net/netdevsim/ethtool.c | 64 +++++++++++ drivers/net/netdevsim/netdev.c | 1 + drivers/net/netdevsim/netdevsim.h | 11 ++ include/linux/ethtool.h | 26 +++++ include/uapi/linux/ethtool_netlink.h | 18 ++- net/ethtool/pause.c | 63 +++++++++- .../drivers/net/netdevsim/ethtool-pause.sh | 108 ++++++++++++++++++ 18 files changed, 462 insertions(+), 8 deletions(-) create mode 100644 drivers/net/netdevsim/ethtool.c create mode 100755 tools/testing/selftests/drivers/net/netdevsim/ethtool-pause.sh -- 2.26.2
