[PATCH 0/3] selftests: bpf: Migrate test_xdp_redirect.sh to test_progs

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.
