Hi Andrew,
Bhaskar is working on enabling a PFE [1] MAC connected to an Aquantia AQR107
PHY [2] on a LS1012AQDS board. Initially I've indicated 2500Base-X too, but it
seems the HW actually works in SGMII mode. The QDS boards are lower volume,
higher spec boards than the RDBs [3], they exercise most of the HW capabilities.
Regards,
Madalin

Hi Andrew,

seems the HW actually works in SGMII mode. The QDS boards are lower volume,
