Speaking of which, whatever happened to MARP?

This in combination with UDLD sounded good to me when I heard about it a 
couple of years ago.

On the subject of UDLD, does anyone know why no mechanism was included in 
10GE for UDLD? In 1GE there is autoneg which fixes this, but it's gone in 
10GE. I just cannot figure out why anyone would actually remove such an 
operationally important feature, and now try to implement it in software 
instead of on the link layer.
