DPDK support in libpcap

[Denis Ovsienko]

Hello all.

libpcap has been implementing DPDK packet capture support for some
time, in that a contributor added this support using DPDK 18.11.  This
code stopped working with later versions of DPDK and still remains
broken.

Would anybody be interested to upgrade pcap-dpdk.c in libpcap to the
latest stable release of DPDK, to confirm whether it works as intended
and maybe even to keep this module better maintained in future?
