Subject: [PATCH AUTOSEL 6.14 549/642] r8169: don't scan PHY addresses > 0

From: Heiner Kallweit <hkallweit1@...il.com>

[ Upstream commit faac69a4ae5abb49e62c79c66b51bb905c9aa5ec ]

The PHY address is a dummy, because r8169 PHY access registers
don't support a PHY address. Therefore scan address 0 only.
