In commit6de6e46d27("cls_flower: Fix inability to match GRE/IPIP packets"), cls_flower was fixed to match an outer packet of a tunneled packet as would be expected, rather than dissecting to the inner packet and matching on that. This fix uncovered several issues in packet matching in mirroring selftests: - in mirror_gre_bridge_1d_vlan.sh and mirror_gre_vlan_bridge_1q.sh, the vlan_ethtype match is copied around as "ip", even as some of the tests are running over ip6gretap. This is fixed by using an "ipv6" for vlan_ethtype in the ip6gretap tests. - in mirror_gre_changes.sh, a filter to count GRE packets is set up to match TTL of 50. This used to trigger in the offloaded datapath, where the envelope TTL was matched, but not in the software datapath, which considered TTL of the inner packet. Now that both match consistently, all the packets were double-counted. This is fixed by marking the filter as skip_hw, leaving only the SW datapath component active.
