While BPF_CALL instructions were tested implicitly by the cBPF-to-eBPF translation, there has not been any tests for BPF_TAIL_CALL instructions. The new test suite includes tests for tail call chaining, tail call count tracking and error paths. It is mainly intended for JIT development and testing.
