From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mateusz Palczewski Date: Tue, 13 Apr 2021 14:19:40 +0000 Subject: [Intel-wired-lan] [PATCH net v2] i40e: fix the restart auto-negotiation after FEC modified Message-ID: <20210413141940.3456-1-mateusz.palczewski@intel.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: intel-wired-lan@osuosl.org List-ID: From: Jaroslaw Gawin 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.
