 SPP provides libpcap-based PMD for dumping packet to a file or retrieve
 it from the file.
-To use PCAP PMD, install ``libpcap-dev`` and enable it.
+``spp_nfv`` and ``spp_pcap`` use ``libpcap-dev`` for packet capture.
+``spp_pcap`` uses ``liblz4-dev`` and ``liblz4-tool`` to compress PCAP file.

 ``text2pcap`` is also required for creating pcap file which
