RE: Management PMA/PMD registers for XAUI


As currently defined, there is only a single PMA in the stack which is
attached to the PMD. An XGXS doesn't have a separate PMA sublayer. I think
we should leave it that way. We already fragment the physical layer into a
lot of sublayers.

Subject: Management PMA/PMD registers for XAUI

When a 10GBase-X PCS is being used as a PHY XGXS, it has a XAUI PMA. 
Should this PMA have all of the Management registers specified (ie. 1.0,
1.1, 1.2&1.3, 1.4, 1.5, 1.8, 1.9)? Or are these registers for the
PMA/PMD that actually tied to the fiber PMD?
