Currently, user space has no way of knowing if a port can be split and into how many ports. This makes it impossible to write generic tests for port split. This patch set adds the port's width as an attribute of a devlink port and exposes the information to user space using a new attribute. Patch #1 prepares mlxsw to pass width information to devlink Patch #2 changes device drivers to pass width information to devlink and exposes it to user space Patch #3 adds a port split test Danielle Ratson (3): mlxsw: Set port width attribute in driver devlink: Add a new devlink port width attribute and pass to netlink selftests: net: Add port split test .../net/ethernet/broadcom/bnxt/bnxt_devlink.c | 2 +- drivers/net/ethernet/intel/ice/ice_devlink.c | 2 +- .../ethernet/mellanox/mlx5/core/en/devlink.c | 4 +- .../net/ethernet/mellanox/mlx5/core/en_rep.c | 2 +- drivers/net/ethernet/mellanox/mlxsw/core.c | 8 +- drivers/net/ethernet/mellanox/mlxsw/core.h | 1 + drivers/net/ethernet/mellanox/mlxsw/minimal.c | 2 +- .../net/ethernet/mellanox/mlxsw/spectrum.c | 1 + .../net/ethernet/mellanox/mlxsw/switchib.c | 2 +- .../net/ethernet/mellanox/mlxsw/switchx2.c | 2 +- .../net/ethernet/netronome/nfp/nfp_devlink.c | 2 +- .../ethernet/pensando/ionic/ionic_devlink.c | 2 +- drivers/net/netdevsim/dev.c | 2 +- include/net/devlink.h | 2 + include/uapi/linux/devlink.h | 2 + net/core/devlink.c | 7 + net/dsa/dsa2.c | 6 +- tools/testing/selftests/net/Makefile | 1 + .../selftests/net/devlink_port_split.py | 259 ++++++++++++++++++ 19 files changed, 292 insertions(+), 17 deletions(-) create mode 100755 tools/testing/selftests/net/devlink_port_split.py -- 2.26.2
