From 85cd45580f5e3b26068cccb7d6173f200e754dc0 Mon Sep 17 00:00:00 2001
From: Daniel Golle <daniel@makrotopia.org>
Date: Sun, 2 Apr 2023 23:56:16 +0100
Subject: [PATCH 1/2] net: phy: realtek: use genphy_soft_reset for 2.5G PHYs
Some vendor bootloaders do weird things with those PHYs which result in
link modes being reported wrongly. Start from a clean sheet by resetting
the PHY.
