[rbridge] Consensus Check: Point to Point links

[Silvano Gai]

Joe,

The majority of RBridges will be deployed in backbone where they will be
connected by point-to-point links. The classical case will be 10GE links
(which are only full-duplex). There will be no bridges between them.

What we are asking is a sentence that guarantees a simplified
interoperability in this case.

I don't see what harm it can do.
