Subject: [PATCH] net: microchip: lan743x: add ethtool nway_reset support
Date: Wed, 18 Feb 2026 20:56:15 +0100	[thread overview]
Message-ID: <20260218195615.25655-1-nb@tipi-net.de> (raw)

Wire phylink_ethtool_nway_reset() as the .nway_reset ethtool operation,
allowing userspace to restart PHY autonegotiation via 'ethtool -r'.
