[nsp] Cat 6509 to 2621 load balancing

[Stephen J. Wilcox]

Cat6xxx really wants to L3 switch your packets.

In short you dont want to do per packet, you need to disable all forms of 
L3/fast switching to make this work. So disable mls, disable ip route-cache and 
it should do the trick but your switch will run badly!
