Hi all,
This patch series continues the work to migrate the script tests into prog_tests.
The test_xsk.sh script tests lots of AF_XDP use cases. The tests it uses are defined in xksxceiver.c. As this script is used to test real hardware, the goal here is to keep it as is and only integrate the tests on veth peers into the test_progs framework. Three tests are flaky on s390 so they won't be integrated to test_progs yet (I'm currently trying to make them more robust).
PATCH 1 & 2 fix some small issues xskxceiver.c PATCH 3 to 9 rework the xskxceiver to ease the integration in the test_progs framework. Two main points are addressed in them :
- wrap kselftest calls behind macros to ease their replacement later
- handle all errors to release resources instead of calling exit() when any error occurs.
PATCH 10 extracts test_xsk[.c/.h] from xskxceiver[.c/.h] to make the tests available to test_progs PATCH 11 enables kselftest de-activation PATCH 12 isolates the flaky tests PATCH 13 integrate the non-flaky tests to the test_progs framework

I realize that I forgot to mention 'bpf-next', sorry about that. This work is based on the bpf-next_base branch.
Best regards, Bastien
