Description (partial)

By default on N7k, we noticed that all uRPF failed packets wil be sent to the CPU on N7k. 
After some research, we found this is expected behavior for Nexus which needed to be changed.

Rather we need these above commands to be added to the default COPP class on higher code levels.
  match exception ip unicast rpf-failure
  match exception ipv6 unicast rpf-failure
