Subject: [PATCH ethtool v3 0/5] Extend uAPI with lanes parameter

Currently, there is no way of knowing how many lanes will be use to
achieve a wanted speed.
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.

v3:
	* Add a seperated patch, patch #1, for uapi headers and squash
	* the rest of it to patch #2.

Danielle Ratson (5):
  update UAPI header copies
  netlink: settings: Add netlink support for lanes parameter
  netlink: settings: Expose the number of lanes in use
  shell-completion: Add completion for lanes
  man: Add man page for setting lanes parameter
