Fman/mEMAC: mEMAC fix for 10G MAC and PHY
1. use Payload length check disable when enable MAC; 2. add XGMII support for setting MAC interface mode; 3. only enable auto negotiation for Non-XGMII mode; 4. return 0xffff if clause 22 is used to read 10G phy_id; Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Acked-By: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: York Sun <yorksun@freescale.com>
