feat(astf): Support framesizes for ASTF
- No support for IMIX. + Fix a bad bug in padding (most ASTF profiles had wrong frame sizes). + Fix a big typo in TCP PPS profiles (s->c was not data, just RST). + Control transaction size via ASTF_N_DATA_FRAMES env variable. - Default value 5 leads to transactions smaller than before. + It ensures transaction is one burst (per direction) even for jumbo. + Edit autogen to set supported frame sizes based on suite id. + Both TCP and UDP use the same values: + 64B for CPS (exact for UDP, nominal for TCP). + 100B, 1518B and 9000B for TPUT and PPS. - TCP TPUT achievable minimum is 70B. + Used 100B to leave room for possible IPv6 ASTF tests. + Separate function for code reused by vpp and trex tests. - I do not really like the new "copy and edit" approach added here. + But it is a quick edit, better autogen refactor is low priority. + Consider both established and transitory sessions as valid. - Mostly for compatibility with 2202 behavior and to avoid ramp-ups. - Assuming both session states have similar enough VPP CPU overhead. + Added a TODO to investigate and maybe reconsider later. + Update the state timeout value to 240s. + That is the default for TCP (for transitory state). - UDP could keep using 300s. + But I prefer UDP and TCP to behave as similarly as possible. + Use TRex tunables to get the exact frame size (for data packets). - It is not clear why the recipe for MSS has to be this complicated. + Move code away from profile init, as frame size is not known there. + Change internal profile API, so values related to MSS are passed. + Lower ramp-up rate for TCP TPUT tests. + Because without lower rate, jumbo fails on packet loss in ramp-up. + UDP TPUT ramp-up rate also lowered (just to keep suites more similar). + Distinguish one-direction and aggregated average frame size. + Update keyword documentation where the distiction matters. + One-direction is needed for turning bandwidth limit to TPS limit. + Aggregated is needed for correct NDRPDR bandwidth result value. - TCP TPUT will always be few percent below bidirectional maximum. + That is unavoidable, as one direction sends more control packets. + Add runtime consistency checks so future refactors are safer. + Fail if padding requested would be negative. + Fail if suite claims unexpected values for packets per transaction. + Edit the 4 types of ASTF profiles to keep them similar to each other. + Move UDP TPUT limit value from a field back to direct argument. + Stop pretending first UDP packet is not data. + Apply small improvements where convenient. + Replace "aggregate" with "aggregated" where possible. + To lower probability of any future typos in variable names. + Avoid calling Set Numeric Frame Sizes twice. + Code formatting, keyword documentation, code comments, ... + Add TODOs for less important code quality improvements. - Postpone updating of methodology pages to a subsequent change.
