We're looking for a standard way to configure PHY loopback on a network interface using common Linux tools like ethtool, ip, or devlink. Currently, ethtool -k eth0 loopback on enables a generic loopback, but it doesn't specify if it's an internal, external, or PHY loopback. Need suggestions to implement this feature in a standard way.
