Matias, can you please add validation test case to that series the same
thing which we use for odp-dpkd?
I.e. with PCAP PMD. to test functionality.
Thanks,
Maxim.

Implements new DPDK pktio type, which operates in the same manner as the
existing ODP interface types. DPDK mbuf packets are copied during receive/send
to maintain compatibility with the linux-generic pktio.
The current unoptimized DPDK pktio implementation achieves forwarding rates
(odp_l2fwd), which are comparable to netmap pktio and scale better with larger
thread counts. Some initial benchmark results below
(odp_l2fwd 4 x 10 Gbps - 64B, Intel Xeon E5-2697v3).
Threads
1 2 4 6 8 10 12
DPDK 6.7 12 25.3 37.2 47.6 47.3 46.8 MPPS
Netmap 6.1 12.6 25.8 32.4 38.9 38.6 38.4
From 8 threads and onwards the throughput is limited by the NICs (Intel 82599).
Build and usage information can be found from DEPENDENCIES. The DPDK
initialization code is copied from the odp-dpdk branch.
