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.
