Currently, when user space queries the link's parameters, as speed and duplex, each parameter is passed from the driver to ethtool. Instead, get the link mode bit in use, and derive each of the parameters from it in ethtool. Signed-off-by: Danielle Ratson <danieller@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
