Create a topology with 3 hosts, a router each in it's own network namespace. Test IPv4 and IPv6 multipath routing from h1 to h2/h3 via router r1 where a multipath route is setup to load-balance between h2 and h3.

See diagram in the test for more information.

How are you running this test? At least with veth pairs it is passing both before and after the patches. I didn't look into the veth driver, it might not even use the listified path.

Also, I'm seeing the following errors during the test:

sysctl: setting key "net.ipv4.fib_multipath_hash_policy": Invalid argument sysctl: setting key "net.ipv6.fib_multipath_hash_policy": Invalid argument
