Subject: [PATCH net-next v12 11/13] net: ethtool: cable-test: Target the command to the requested PHY
Date: Wed,  5 Jun 2024 14:49:16 +0200
Message-ID: <20240605124920.720690-12-maxime.chevallier@bootlin.com>

Cable testing is a PHY-specific command. Instead of targeting the command
towards dev->phydev, use the request to pick the targeted PHY.
