Re: XAUI and 64b/66b
Rich,
I saw this mapping in another email last night but I guess I
was confused as I didn't think it solved our problem. This
appears to be a map of XGMII or XAUI codes to 8b10b code-groups.
This does not appear to be a map of XGMII or XAUI codes to
64b/66b codes. I've already seen the mapping to XAUI. I'm
waiting to see the mapping to 64b/66b.

And as for the lightweight part, I know better. I was sitting
there but it wasn't me that made that statement...
