Subject: [PATCH 40/42] netlink: settings: Expose the number of lanes in use
|
|
|
91be6c |
|
|
|
91be6c |
Currently, the user does not have the information regarding how many lanes
|
|
|
91be6c |
are used when the link is up.
|
|
|
91be6c |
|
|
|
91be6c |
After adding a possibility to advertise or force a specific number of
|
|
|
91be6c |
lanes this information becomes helpful.
|
|
|
91be6c |
|
|
|
91be6c |
Expose the number of lanes in use if the information is passed from
|
|
|
91be6c |
kernel.
