track the physical port in the pipeline

[Balakrishnan K]

Hi All,
    Is there any configuration or struct store the physical port where the packet is comes in.
Trying below scenario:
I have two pipeline in pipeline1 reading the packets from two links.
Link 0 bound to port 0 and link 1 bound to port 1.
After reading the packets in the pipeline 1 doing the packets match and action using tables.
Finally, it will be sent to pipeline2.
Pipeline2 forward the packets to another physical port.
If packets received in physical port 0 need to forward the traffic to port 2.
If the packets received in physical port 1 need to forward the traffic to port3.

I am unable to decide the out port because packets doesn't info about the port in.
Is there any option available to track the physical port_in?
Any help would be appreciated.


Regards,
Bala
