[j-nsp] Implementing Ethernet Aggregated Features

[Gary Hauser]

Not to mention that the FXP1 interface is not a physical interface in
the since of having a pluggable interface (RJ45) it is only for
communication over the backplane as Jeremy stated.

The fxp1 interface is the link between the RE and the PFE and shouldn't
ever be touched by any configuration attempts.  This could mess up
communication between the RE and PFE and cause problems with the routers
functionality.

FXP0 is the out of band management interface and each RE in a router has
one.  The M40 only has one out of band management interface, because it
only has one RE.
