From df006dd4b1dca8c486f73ae76fb77c06afae83f2 Mon Sep 17 00:00:00 2001 From: Dave Ertman Date: Fri, 20 Nov 2020 16:39:26 -0800 Subject: ice: Add initial support framework for LAG Add the framework and initial implementation for receiving and processing netdev bonding events. This is only the software support and the implementation of the HW offload for bonding support will be coming at a later time. There are some architectural gaps that need to be closed before that happens. Because this is a software only solution that supports in kernel bonding, SR-IOV is not supported with this implementation.
