Hi all,
This patch series continues the work to migrate the *.sh tests into prog_tests.
test_xdp_redirect.sh tests the XDP redirections done through bpf_redirect().
These XDP redirections are already tested by prog_tests/xdp_do_redirect.c but IMO it doesn't cover the exact same code path because xdp_do_redirect.c uses bpf_prog_test_run_opts() to trigger redirections of 'fake packets' while test_xdp_redirect.sh redirects packets coming from the network. Also, the test_xdp_redirect.sh script tests the redirections with both SKB and DRV modes while xdp_do_redirect.c only tests the DRV mode.
The patch series adds two new test cases in prog_tests/xdp_do_redirect.c to replace the test_xdp_redirect.sh script.
