For example, 100G speed can be achieved using: 2X50 or 4X25. In order to solve that, extend ethtool uAPI with lanes as a new link mode setting so the command below, for example, will be supported: $ ethtool -s swp5 lanes N Patch #1: Update headers with the new parameter. Patch #2: Support lanes in netlink. Patch #3: Expose the number of lanes in use. Patch #4: Add auto-completion for lanes. Patch #5: Add lanes to man page.
