Thanks Oli, also it appears that you must police in 64 k increments... But
why doesn't it change the burst when I police at 192 kbps, but it does
change burst when I police at 256 kbps... ?  1598 * 2 = 3196....
interestingly it added one more byte... 3197....then when I go up to 64 k
more, it added 2 bytes.  But when I added the next 64 k increment to 384 k
policing it goes to exactly 1598 * 3 = 4794 !  Does any of that make sense?
...is it explainable somehow ?  maybe there is a document somewhere with a
scale chart that shows at each increment what it will do for built-in burst
values and why.
