test_bpf: add bpf_skb_vlan_push/pop() tests
improve accuracy of timing in test_bpf and add two stress tests: - {skb->data[0], get_smp_processor_id} repeated 2k times - {skb->data[0], vlan_push} x 68 followed by {skb->data[0], vlan_pop} x 68 1st test is useful to test performance of JIT implementation of BPF_LD_ABS together with BPF_CALL instructions. 2nd test is stressing skb_vlan_push/pop logic together with skb->data access via BPF_LD_ABS insn which checks that re-caching of skb->data is done correctly. In order to call bpf_skb_vlan_push() from test_bpf.ko have to add three export_symbol_gpl. Signed-off-by: Alexei Starovoitov <> Signed-off-by: David S. Miller <>
