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 with verbose level 4.

Seq#   Time        Port:Que R Description
     1 0.000000000    0:0   R :: → ff02::16 ICMP 143
     2 0.000000000    0:0   R :: → ff02::1:ffbc:89e5 ICMP 135
     3 0.000000000    0:0   R :: → ff02::16 ICMP 143

    40 4.635138535    0:0   T fe80::7442:55ff:febc:89e5 → ff02::2 ICMPv6 Router Solicitation

v4 - add direction flag to output
   - fix build on Windows

Stephen Hemminger (3):
  net: add new packet dissector
  test: add test for packet dissector
  test-pmd: add more packet verbose decode options
