net: filter: additional BPF tests
All tests should pass with and without JIT. Example output: test_bpf: #0 TAX 35 16 16 PASS test_bpf: #1 TXA 7 7 7 PASS test_bpf: #2 ADD_SUB_MUL_K 10 PASS test_bpf: #3 DIV_KX 33 PASS test_bpf: #4 AND_OR_LSH_K 10 10 PASS test_bpf: #5 LD_IND 8 8 8 PASS test_bpf: #6 LD_ABS 8 8 8 PASS test_bpf: #7 LD_ABS_LL 13 14 PASS test_bpf: #8 LD_IND_LL 12 12 12 PASS test_bpf: #9 LD_ABS_NET 10 12 PASS test_bpf: #10 LD_IND_NET 11 12 12 PASS ... Numbers are times in nsec per filter for given input data. Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S. Miller <davem@davemloft.net>
