From eebc26d9947ea9b9008b6d154982fe28305abab3 Mon Sep 17 00:00:00 2001 From: Harman Kalra Date: Wed, 23 Jun 2021 01:35:54 +0530 Subject: [PATCH] net/octeontx2: support link status Adding a new callback for reading the link status. PF can read it's link status and can forward the same to VF once it comes up.
