This patch adds new test to our regression_tests phase3. The topology is the same as in phase1 simple_netperf test.

This test covers performance of ipsec over ethernet. Ping and netperf is run. Covered are both tunnel and transport mode. All tests are done with esp, ah and comp options set together. All combinations of cipher and hash functions listed below are tested. Netperf message size is set to 1400 bytes by default.

ciphers: aes, des, des3_ede, cast5, blowfish, serpent, twofish hash functions: hmac(md5), sha1, sha256

--- Changes in v2: * removed whitespaces and static thresholds

v3: * default nperf_msg_size set to 16000 * added set mtu to nic * msg_size added as result parameter to perfrepo * repaired bad indentation * default mtu set to 1500 * removed one fragmentation check

v4: * reworked compression check * removed typically unused cipher algorithms and hash functions --- .../phase3/ipsec_esp_ah_comp.README | 98 ++++ .../regression_tests/phase3/ipsec_esp_ah_comp.py | 535 +++++++++++++++++++++ .../regression_tests/phase3/ipsec_esp_ah_comp.xml | 50 ++ 3 files changed, 683 insertions(+) create mode 100644 recipes/regression_tests/phase3/ipsec_esp_ah_comp.README create mode 100644 recipes/regression_tests/phase3/ipsec_esp_ah_comp.py create mode 100644 recipes/regression_tests/phase3/ipsec_esp_ah_comp.xml
