This series adds TCP payload verification to udpgso_bench_rx and
exercises it from udpgso_bench.sh for both IPv4 and IPv6. The test
checks the receiver's exit status so that verification errors are
reported as test failures.

Changes since v2:
- Wrap the receiver command in patch 2 to stay within 80 columns.

v2: https://lore.kernel.org/r/20260911160649.51863-1-f64116045@gs.ncku.edu.tw

Changes since v1:
- Add patch 2 to exercise the TCP verifier from udpgso_bench.sh,
  addressing Jakub's feedback.

v1: https://lore.kernel.org/r/20260906145643.219609-1-f64116045@gs.ncku.edu.tw

Testing (v2):
- udpgso_bench.sh: PASS=22 SKIP=0 FAIL=0.

No full kernel build or boot of a patched net-next kernel was performed.

I think you did not answer the more fundamental question there: why is 
this useful? I don't see much value on top of the existing GRO (h/w) 
tests, while this add a bunch of testscase/runtime/resource usage on the 
CI from now on.

In the current format it's IMHO not worth merging.
