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.
