From 85cd45580f5e3b26068cccb7d6173f200e754dc0 Mon Sep 17 00:00:00 2001 From: Daniel Golle 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.
