Guys, I'm facing the same problem as explained by someone else in this thread ( https://lists.fd.io/pipermail/vpp-dev/2016-June/001445.html ) which is not solved.
Actually, I'm just trying to generate some TCP traffic and it "works" by removing "TCP: sport -> dport" and "SYN" lines. Well... by it "works" I mean it almost works. As mentioned in the thread, checksums are wrong. I deeply investigated src/vnet/tcp/tcp_pg.c and more precisely unformat_pg_tcp_header function. Looking at the code, it seems that both "SYN" and "TCP: sport -> dport" should be accepted, while "TCP saddr -> daddr" shouldn't (can't see any unformat for it in there). I thought it would work the same way as UDP, which seems to be the case or at least the expected behavior. What am I missing here ? The source code I'm looking at is the 17.10 version, while I'm running my test from binaries (v17.10-rc2~14-g116af21~b44). Thanks !
