[c-nsp] gigabit ports/modules for 7507 and 7513 routers

[Howard Leadmon]

 On that topic, does anyone know what type of real world throughput one should
be able to get on the onboard GE ports?  I know they aren't limited by the PCI
bus, as they are built in, but can they be run full bore, or anything close to
it?
