2018-08-07selftests: forwarding: gre_multipath: Update next-hop statistics match criteriaGravatar Nir Dotan 1-4/+4
gre_multipath test was using egress vlan_id matching on flows, for the purpose of collecting next-hops statistics, later to be compared against configured weights. As matching on vlan_id on egress direction is not supported on all HW devices, change the match criteria to use destination IP.

2018-07-23selftests: forwarding: gre_multipath: Drop IPv6 testsGravatar Petr Machata 1-107/+6
Support for device-only IPv6 multipath next hops was dropped in commit 33bd5ac54dc4 ("net/ipv6: Revert attempt to simplify route replace and append") and as of commit b5d2d75e079a ("net/ipv6: Do not allow device only routes via the multipath API"), attempts to add a next hop like that yield an explicit diagnostic. Correspondingly, drop the IPv6 parts of GRE multipath test that are supposed to test that code.

2018-06-27selftests: forwarding: Test multipath tunnelingGravatar Petr Machata 1-0/+354
Add a GRE-tunneling test such that there are two tunnels involved, with a multipath route listing both as next hops. Similarly to router_multipath.sh, test that the distribution of traffic to the tunnels honors the configured weights.
