It does either 1Gbps or 10Gbps (over SFP+), depending which bitstream is loaded
into the  FPGA. In the current setup I could also just have two
different compatible
strings, since neither setup supports the other rate, but that might change.

It seems getting rid of that part (the default values) now works, too.

I'll need to take a closer look tomorrow (and I need to retest with 1Gbps)

Will do.

Thanks for feedback,
