One option is to modify the applications to use DPDK's multi-process
support: https://doc.dpdk.org/guides/prog_guide/multi_proc_support.html
Essentially you would have one app read from the real port and then write
data to a software queue in shared memory. Instead of having the second app
read from a port it would read from the queue.
If you want to build more elaborate combinations of functions, check out
our OpenNetVM research project which focused on high performance NF
chaining: http://sdnfv.github.io/onvm/
