[PATCH AUTOSEL 4.19 12/68] selftests: forwarding: gre_multipath: Fix flower filters

by Sasha Levin

From: Ido Schimmel <idosch(a)mellanox.com> [ Upstream commit 1be79d89b7ae96e004911bd228ce8c2b5cc6415f ] The TC filters used in the test do not work with veth devices because the outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw netdevs since the hardware always looks at "The first Ethertype that does not point to either: VLAN, CNTAG or configurable Ethertype". Fix this by matching on the VLAN ID instead, but on the ingress side. The reason why this is not performed at egress is explained in the commit cited below.
