RE: [802.3ae] Proving PMD feasibility

Thank you, Bob. With this message, I am extending an open invitation to all
PMD implementers and link model experts who would be interested in helping
with this project of proving PMD feasibility - let's meet on Monday, 4 pm,
July 9, at the Portland Marriott Downtown, near the reception desk. Also,
please keep checking the notice boards, just in case I am able to arrange a
meeting room. Our agenda will be to agree on the scope of the project and
distribute ownership of various tasks.
