Hello,
this small series aims to increase coverage of xdp features in
test_progs. The initial versions proposed to rework test_xdp_features.sh
to make it fit in test_progs, but some discussions in v1 and v2 showed
that the script is still needed as a standalone tool. So this new
revision lets test_xdp_features.sh as-is, and rather adds missing
coverage in existing test (cpu map). The new revision is now also a
follow-up to the update performed by Florian Kauer in [1] for devmap
programs testing.

Changes in v3:
- Drop xdp_features rework commit
- update xdp_cpumap_attach to extend its coverage
- Link to v2: https://lore.kernel.org/r/20240910-convert_xdp_tests-v2-1-a46367c9d038@bootlin.com
Changes in v2:
- fix endianness management in userspace packet parsing (call htonl on
constant rather than packet part)
The new test has been run in a local x86 environment and in CI:
#560/1 xdp_cpumap_attach/CPUMAP with programs in entries:OK
#560/2 xdp_cpumap_attach/CPUMAP with frags programs in entries:OK
#560/3 xdp_cpumap_attach/CPUMAP attach with programs in entries on veth:OK
#560 xdp_cpumap_attach:OK
Summary: 1/3 PASSED, 0 SKIPPED, 0 FAILED
