Right about the optical/electrical paths.

We used the stratix dev kit at nyu, with a standard 100Gb QSFP adapter.

        - thx, I will add this figure.  I assume Stratix to SRTM is optical,
SRTM to SRTM Tester is electrical(?), and Tester back to Stratix is
optical again?
        - Also, by "Stratix" you mean devkit or LASP Preprototype?

        - there are labels on the figure itself (admittedly a bit small, but I
think visible)

        - right, the PO "froze P6" for this review just before the U Az BCP, so
it is not included in these slides
