Re: XAUI and 64b/66b
Ben,
aaaaahhhhhhhh :). My head is starting to hurt :)!
Are you saying we just use 64b/66b rather then 8b10b all the way through from the mac
to the phy? Why not do this or why do this?
Sorry for perhaps reading this wrong .... but you have to admit, we need video
reflectors :).
Take care
Joel
