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. v7 - change rte_dissect to return number of characters that would be printed (same as snprintf). And tests around that. v6 - validate result of rte_dissect for simple packet v5 - breakout the additional ICMP types into header - fix some decoding bugs in ARP and ICMP Stephen Hemminger (4): net: add more icmp types net: add new packet dissector test: add test for packet dissector test-pmd: add more packet verbose decode options app/test-pmd/cmdline_flow.c | 3 +- app/test-pmd/config.c | 33 +- app/test-pmd/testpmd.h | 11 + app/test-pmd/util.c | 77 +++- app/test/meson.build | 1 + app/test/test_dissect.c | 302 ++++++++++++++ doc/guides/testpmd_app_ug/testpmd_funcs.rst | 5 +- lib/net/meson.build | 2 + lib/net/rte_dissect.c | 428 ++++++++++++++++++++ lib/net/rte_dissect.h | 45 ++ lib/net/rte_icmp.h | 22 +- lib/net/version.map | 7 + 12 files changed, 914 insertions(+), 22 deletions(-) create mode 100644 app/test/test_dissect.c create mode 100644 lib/net/rte_dissect.c create mode 100644 lib/net/rte_dissect.h
