Linville" <linville@...driver.com>, Vidya Sagar Ravipati <vidya@...ulusnetworks.com>, Saeed Mahameed <saeedm@...lanox.com> Cc: David Decotigny <decot@...glers.com>, Ben Hutchings <ben@...adent.org.uk>, Gal Pressman <galp@...lanox.com> Subject: [PATCH RFC 0/2] ethtool: Add actual port speed reporting Sending RFC to get feedback for the following ethtool proposal: In some cases such as virtual machines and multi functions (SR-IOV), the actual bandwidth exposed for each machine is not accurately shown in ethtool. Currently ethtool shows only physical port link speed. In our case we would like to show the virtual port operational link speed which in some cases is less than the physical port speed. This will give users better visibility for the actual speed running on their device. $ ethtool ens6 ... Speed: 50000Mb/s Actual speed: 25000Mb/s Gal Pressman (2): ethtool: Add get actual port speed support net/mlx5e: Add support for ethtool get actual speed callback drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c | 7 +++++++ include/linux/ethtool.h | 1 + include/uapi/linux/ethtool.h | 2 ++ net/core/ethtool.c | 20 ++++++++++++++++++++ 4 files changed, 30 insertions(+) -- 2.7.4
