From 61343e6da7810de81d6b826698946ae4f9070819 Mon Sep 17 00:00:00 2001 From: Jaroslaw Gawin Date: Tue, 13 Apr 2021 14:19:40 +0000 Subject: i40e: fix the restart auto-negotiation after FEC modified When FEC mode was changed the link didn't know it because the link was not reset and new parameters were not negotiated. Set a flag 'I40E_AQ_PHY_ENABLE_ATOMIC_LINK' in 'abilities' to restart the link and make it run with the new settings.
