Thanks Andrew, Lee for the feedback.

Lee,
I don't see prbs11.0, prbs11.1, prbs11.2, prbs11.3, prbs13.0, prbs13.1, prbs13.2, prbs13.3, prbs16 and prbs32 in IEEE 802.3 2022 standard.
Is this specific to fnic based on base PRBS pattern or it is mentioned in some other standard ?

Those were from the fbnic spec, I'm not sure where they originate from. I
suppose we can drop those for now but its good to keep in mind more tests
may be added in the future.

Can you find out what they actually do. It might be something as silly
as, the .1 indicate it only runs on lane 1? So these are in fact
standard prbs11 and being able to specify the lane via another
attribute is sufficient?
