[PATCH net-next v10 10/13] net: ethtool: pse-pd: Target the command to the requested PHY

From: Maxime Chevallier
Date: Mon Mar 04 2024 - 10:14:30 EST


PSE and PD configuration is a PHY-specific command. Instead of targeting
the command towards dev->phydev, use the request to pick the targeted
PHY device.
