From 3b2de56a146f34e3f70a84cc3a1897064e445d16 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Fri, 16 Jun 2023 13:06:43 +0100 Subject: [PATCH] net: pcs: lynxi: update PCS driver to use neg_mode Update the Lynxi PCS driver to use neg_mode rather than the mode argument. This ensures that the link_up() method will always program the speed and duplex when negotiation is disabled.
