[STA Members] Follow up SAS Plugfest discussion

To help with this discussion, UNH-IOL has put together a matrix of the 
possible Phy capabilities that a device could potentially support, see 
the attached spreadsheet.

What the matrix shows is that at a single speed, there are 8 possible phy 
configurations, not including different settings for amplitude, 
pre-empahsis, and equalization.

I'd like to hear what the best way to delineate (i.e. high medium low or 
specific values) these other three settings are ( amplitude, pre-emphasis, 
equalization ) This way we can determine all the possible phy 
configuration permutations. As you can see this will lead to a big number 
of test runs, much more than could be accomplished during 1 week. The next 
step will be to whittle down to the most interesting 4-5 combinations.
