The function do_test_span_vlan_dir_ips() is used for testing whether mirrored packets are VLAN-encapsulated. But since it only considers VLAN encapsulation, it may end up matching unmirrored ARP traffic as well. One consequence is a rare failure of mirror_gre_vlan_bridge_1q's test_gretap_untagged_egress. Decreasing ping cadence in mirror_test() makes the problem easily reproducible. Therefore tighten up the match criterion to only count those 802.1q packets where the next header is IP.
