Stanislav Fomichev 7b8a130432 bpf: when doing BPF_PROG_TEST_RUN for flow dissector use no-skb mode ... Now that we have bpf_flow_dissect which can work on raw data, use it when doing BPF_PROG_TEST_RUN for flow dissector. Simplifies bpf_prog_test_run_flow_dissector and allows us to test no-skb mode. Note, that previously, with bpf_flow_dissect_skb we used to call eth_type_trans which pulled L2 (ETH_HLEN) header and we explicitly called skb_reset_network_header. That means flow_keys->nhoff would be initialized to 0 (skb_network_offset) in init_flow_keys. Now we call bpf_flow_dissect with nhoff set to ETH_HLEN and need to undo it once the dissection is done to preserve the existing behavior.
