While debugging TAP rte_flow discovered that test pmd verbose output
was confusing and unhelpful. Instead, made a simple dissector that
prints one line per packet like this in test-pmd.

Also supports hex and JSON mode when more detail is needed.

The new commands are:
	testpmd> set output /tmp/packet.log
	testpmd> set format dissect

To enable packet logging need to use:
	testpmd> set verbose 3

v10 - rebase based on changes to lib/net and cmdline

Stephen Hemminger (8):
  net: add more icmp types
  net: add new packet dissector
  mbuf: decode the hash and fdir info in rte_pktmbuf_dump
  test: add test for packet dissector
  test-pmd: add option to redirect packet log
  test-pmd: add hex decode
  test-pmd: add packet dissect format
  test-pmd: add a JSON packet output
