tc-testing: add selftests for 'bpf' action
Test d959: Add cBPF action with valid bytecode Test f84a: Add cBPF action with invalid bytecode Test e939: Add eBPF action with valid object-file Test 282d: Add eBPF action with invalid object-file Test d819: Replace cBPF bytecode and action control Test 6ae3: Delete cBPF action Test 3e0d: List cBPF actions Test 55ce: Flush BPF actions Test ccc3: Add cBPF action with duplicate index Test 89c7: Add cBPF action with invalid index Test 7ab9: Add cBPF action with cookie Changes since v1: - use index=2^32-1 in test ccc3, add tests 7a89, 89c7 (thanks Roman Mashak) - added test 282d Signed-off-by: Davide Caratti <dcaratti@redhat.com> Signed-off-by: David S.
