At my request our chief editor has developed a list of TBD items found in IEEE P802.3cw D1.0. (The list is at the end of this email.)
I would like to thank Tom for this effort, as it will help us to focus on working towards a technically complete draft.
Please review this list and consider possible comments as you review D1.0 for our initial Task Force Review.
