Subject: [PATCH net-next v6 11/13] net: ethtool: cable-test: Target the command to the requested PHY

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

Signed-off-by: Maxime Chevallier <maxime.chevallier@...tlin.com>

V6: Use dedicated policy
V5: Added Andrew's R-b
V4: No changes
V3: No changes
V2: New patch
