From 1dfb92a529722c87b251eaaf673c48b13d1a54cc Mon Sep 17 00:00:00 2001 From: Igor Romanov Date: Mon, 11 Oct 2021 17:48:39 +0300 Subject: [PATCH] net/sfc: implement port representor link update Implement the callback by reporting link down if the representor is not started, otherwise report link up with undefined link speed. Link speed is undefined since representors can pass traffic to each other even if the PF link is down.
