"For my part, if we were going to allow OAM to be an option, I would
strongly prefer that it be an option like 802.3ad, which a customer
can readily identify as a supported feature on a spec sheet, and not
an option that is buried in a PIC table and not readily exposed to the buyer."
From the stand point of 802.3 all we have control over is a standard,
revision to a standard, or amendment to a standard with clauses including pix tables!
We have little control, except via management, of how pix options
appear to the customer in a product ipmlementation.
