[PATCH net-next 3/9] selftests/tc-testings: add selftests for bpf filter

From: Zhengchao Shao
Date: Tue Sep 13 2022 - 00:22:14 EST


Test 23c3: Add cBPF filter with valid bytecode
Test 1563: Add cBPF filter with invalid bytecode
Test 2334: Add eBPF filter with valid object-file
Test 2373: Add eBPF filter with invalid object-file
Test 4423: Replace cBPF bytecode
Test 5122: Delete cBPF filter
Test e0a9: List cBPF filters
