The program up if you want to have a look. I am still working on the guidelines for use.

My testing has been principally focused on the i354. I will also be testing the i211, which I believe should be very close to the i210, but I need to finish the i354 first. Unfortunately it’s a long iterative process to balance the tx and rx values.

I have a program that will test this for you. Give me a few days to finish cleaning it up.

With no compensation I see now delay of about 1450 ns between two i210
NICs.
