Currently, when user space queries the link's parameters, as speed and duplex, each parameter is passed from the driver to ethtool. Instead, pass the link mode bit in use. In Spectrum-1, simply pass the bit that is set to '1' from PTYS register. In Spectrum-2, pass the first link mode bit in the mask of the used link mode. Signed-off-by: Danielle Ratson <danieller@nvidia.com> --- Notes: v2: * Reword commit message. * Pass link mode bit to ethtool instead of link parameters. * Use u32 for lanes param instead ETHTOOL_LANES defines. .../net/ethernet/mellanox/mlxsw/spectrum.h | 6 +-- .../mellanox/mlxsw/spectrum_ethtool.c | 47 +++++++++++-------- 2 files changed, 30 insertions(+), 23 deletions(-)
