test_bpf: fix the dummy skb after dissector changes
Commit d5709f7ab776 ("flow_dissector: For stripped vlan, get vlan info from skb->vlan_tci") made flow dissector look at vlan_proto when vlan is present. Since test_bpf sets skb->vlan_tci to ~0 (including VLAN_TAG_PRESENT) we have to populate skb->vlan_proto. Fixes false negative on test #24: test_bpf: #24 LD_PAYLOAD_OFF jited:0 175 ret 0 != 42 FAIL (1 times) Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Dinan Gunawardena <dinan.gunawardena@netronome.com> Acked-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.
