New to P4

[Raghav Kapoor]

Hello, 

I'm trying to build a simple wire P4 application using a modification of the port_to_port code from the p4wire repository. I modified the p4cfg file, so that the table only has one rule where any packets received on the port 0 are sent back out through port 0. But, I'm not having any luck receiving any packets after they are sent. I would appreciate advice on how to debug this issue. 

Thank you.
