[nsp] 6500 Native IOS ACLs

[Rubens Kuhl Jr.]

Is RPF checking enabled on any interface ? This halves maximum FIB size to
112,000 routes... replacing RPF with inbound ACLs removes this limitation.
Even if it's not your current problem, it will haunt you very soon unless
you filter a lot of routes and default them.
