Daniel Borkmann ccd9a8be2e selftests/bpf: Add various more tcx test cases
Add several new tcx test cases to improve test coverage. This also includes
a few new tests with ingress instead of clsact qdisc, to cover the fix from
commit dc644b540a ("tcx: Fix splat in ingress_destroy upon tcx_entry_free").
