Clean up dpdk plugin rx/tx pcap tracing
Needed a spinlock to protect the data vector. Cleaned up debug cli so the output makes sense, and so that various parameters exist in one place. Removed a nonsense memset-to-zero which led to ultra-confusing results. Change-Id: I91cd14ce7fe84fd2eceab86e016b5ee001993be4 Signed-off-by: Dave Barach <dbarach@cisco.com>
