Hi Dave and others, I was under the impression that "ten_Gbe_v2" was suppose to support ROACH2 as well. At least, its mask supports parameters specific to ROACH2 (such as choice between CX4, SFP+ and ports etc.). Rather, these options are available in the mask only for ROACH2.
Is "10_Gbe_v2" part of SKA-SA github repository now and is that supposed to be used instead of "ten_Gbe_v2"? I have not updated the repository of late and have been using ten_Gbe_v2 for my ROACH2 design.
