Hi Andrew,
I think there is a disconnect here.

Which proves my point. The specification is not sufficient if you have
to keep correcting me.

The kAPI should be understandable by somebody who has a general
networking background. Please write a specification with that
assumption in mind. Don't assume the reader is a test engineer who has
used PRBS for half his life. Assume it is a brand new test engineer
who is hearing PRBS for the first time. That is what most engineers on
the netdev list are. Me included.

I think part of the disconnect is that PRBS testing is a signal 
integrity test, not a network test. In this case the phy happens to be 
Ethernet but it could just as easily be PCIE or USB. That is why it was 
heavily suggested to me at netdev 0x19 that this should be done on the 
generic phy layer, not netdev.
