Packetdrill throws a "bad outbound TCP options" error when an outbound packet contains mpc+datalen. The data length field shows up "unknown length" in the actual packet.

the problem is, packetdrill does not support MPC+DATA+checksum at all. I'm working on extending the current code to support it

I suggest to convert this as a "new feature": we need to support MPC+DATA+checksum. Please tell me if it is not OK!

selftests/bpf: Add various more tcx test cases
ccd9a8b 
Add several new tcx test cases to improve test coverage. This also includes
a few new tests with ingress instead of clsact qdisc, to cover the fix from
commit dc644b5 ("tcx: Fix splat in ingress_destroy upon tcx_entry_free").
