How about a Perl/Python script to generate a PCAP file with random packets and then feed the PCAP file to the PCAP PMD?
Random can mean different requirements for different users/application, I think it is difficult to fit this under a simple generic API. Customizing the script for different requirements if a far better option in my opinion.
