4.18-stable review patch. If anyone has any objections, please let me know.

From: Petr Machata <petrm@xxxxxxxxxxxx>
[ Upstream commit ec9fdc99f5a6a2cfe4061e807fcb0cc1129f0a2d ]
When running mirror_gre_bridge_1d_vlan tests on veth, several issues
cause spurious failures:
- vlan_ethtype should be ip, not ipv6 even in mirror-to-ip6gretap case,
because the overlay packet is still IPv4.
- Similarly ip_proto matches the innermost IP protocol, so can't be used
to filter out GRE packet. Drop the corresponding condition.
- Because the above fixes the filters to match in slow path as well,
they need to be made skip_hw so as not to double-count packets.
