Toke Høiland-Jørgensen	adfd272c4c	bpf, selftests: Extend test_tc_redirect to use modified bpf_redirect_neigh() This updates the test_tc_neigh prog in selftests to use the new syntax of bpf_redirect_neigh(). To exercise the helper both with and without the optional parameter, add an additional test_tc_neigh_fib test program, which does a bpf_fib_lookup() followed by a call to bpf_redirect_neigh() instead of looking up the ifindex in a map. Update the test_tc_redirect.sh script to run both versions of the test, and while we're add it, fix it to work on systems that have a consolidated dual-stack 'ping' binary instead of separate ping/ping6 versions.

bpf, selftests: Extend test_tc_redirect to use modified bpf_redirect_neigh()

This updates the test_tc_neigh prog in selftests to use the new syntax of
bpf_redirect_neigh(). To exercise the helper both with and without the
optional parameter, add an additional test_tc_neigh_fib test program, which
does a bpf_fib_lookup() followed by a call to bpf_redirect_neigh() instead
of looking up the ifindex in a map.

Update the test_tc_redirect.sh script to run both versions of the test,
and while we're add it, fix it to work on systems that have a consolidated
dual-stack 'ping' binary instead of separate ping/ping6 versions.

Rename into test_tc_redirect.sh and move setup and test code into separate
functions so they can be reused for newly added tests in here. Also remove
the crude hack to override ifindex inside the object file via xxd and sed
and just use a simple map instead. Map given iproute2 does not support BTF
fully and therefore neither global data at this point.
