Altera TSE: Add support for no PHY
This patch avoids PHY and MDIO probing if no PHY chip is present. This is the case mainly in optical links where there is no need for PHY chip, and therefore no need of MDIO. In this scenario Ethernet MAC is directly connected to an optical module through an external SFP transceiver. Signed-off-by: Walter Lozano <walter@vanguardiasur.com.ar> Signed-off-by: David S.
