test_bpf: reduce MAX_TESTRUNS
For tests that are using the maximal number of BPF instruction, each run takes 20 usec. Looping 10,000 times on them totals 200 ms, which is bad when the loop is not preemptible. test_bpf: #264 BPF_MAXINSNS: Call heavy transformations jited:1 19248 18548 PASS test_bpf: #269 BPF_MAXINSNS: ld_abs+get_processor_id jited:1 20896 PASS Lets divide by ten the number of iterations, so that max latency is 20ms. We could use need_resched() to break the loop earlier if we believe 20 ms is too much. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
