net: ibm: emac: support RGMII-[RX|TX]ID phymode
The RGMII spec allows compliance for devices that implement an internal delay on TXC and/or RXC inside the transmitter. This patch adds the necessary RGMII_[RX|TX]ID mode code to handle such PHYs with the emac driver. Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: David S.
