Message-ID: <20250704130624.372651-1-piotr.kwapulinski@intel.com> Date: Fri, 4 Jul 2025 15:06:24 +0200 From: Piotr Kwapulinski <piotr.kwapulinski@...el.com> To: intel-wired-lan@...ts.osuosl.org Cc: netdev@...r.kernel.org, andrew@...n.ch, pmenzel@...gen.mpg.de, Piotr Kwapulinski <piotr.kwapulinski@...el.com>, Przemek Kitszel <przemyslaw.kitszel@...el.com> Subject: [iwl-next v2] ixgbe: add the 2.5G and 5G speeds in auto-negotiation for E610 The auto-negotiation limitation for 2.5G and 5G speeds is no longer true for X550 successors like E610 adapter. Enable the 2.5G and 5G speeds in auto-negotiation for E610 at driver load.
