From 53e33fe5f4f982afe13e45677d134eb1b11d4d2a Mon Sep 17 00:00:00 2001 From: Danielle Ratson Date: Wed, 10 Feb 2021 15:48:38 +0200 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.
