Hello, I've been struggling with the following issue (observed with VPP 21.01): when trying any of ASTF TRex profiles with VPP, I get multiple errors: "ip4 length > l2 length". These don't happen with each packet but rather with some of them. It looks like the TCP payload is truncated down to 600 bytes for some reason, while looking at the TRex simulation, it should be 1448 bytes. I have collected a snippet from dispatch trace dissected by Wireshark and other info here: https://gist.github.com/ivan4th/e0130dac619f91a6bb8e7987550c2466 I'm not really sure this is VPP and not a TRex issue, especially given that it's only seen in ASTF mode of TRex, but I'm asking it here b/c (1) TRex is used for CSIT (2) There's an old open ticket for a similar CSIT problem: https://jira.fd.io/browse/VPP-1676 Not sure if it was resolved somehow already.
Passing --tso-disable --lro-disable --checksum-offload-disable flags to TRex doesn't change anything. If there's no known solution for this issue, I'll dig into it myself, but I'd like to ask if maybe it was already solved by someone.
