Subject: [PATCH 40/42] netlink: settings: Expose the number of lanes in use

Currently, the user does not have the information regarding how many lanes
are used when the link is up.

After adding a possibility to advertise or force a specific number of
lanes this information becomes helpful.

Expose the number of lanes in use if the information is passed from
kernel.
