net: stmmac: selftests: Do not fail if PHY is not attached
If a PHY is not attached, we can still run the tests with MAC loopback mode. Return -EOPNOTSUPP error code in PHY loopback test so that global status is not a failure. Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
