Seems like you are having less ports than specified in l2fwd.cfg. In order to run ip_pipeline with l2fwd.cfg configuration file, 4 ports are required.  So , you can either change configuration file and remove 3 extra ports (RXQ1.0, RXQ2.0, RXQ3.0 and TXQ1.0, TXQ2.0, TXQ3.0)  or bind 3 more ports to dpdk and use the default l2fwd.cfg straightaway.
