Re: [dpdk-users] [dpdk-dev] Working of pipeline in a given config file and regarding user-defined actions in IP_PIPELINE application

Hi Cristian,

Thanks for your help.

If that is the case, is there any way to use the incoming port as a key for
table lookup? I need to use incoming port along with some other fields of
each packet as the key for my application.
