Subject: [PATCH v5 net-next 0/3] net: multipath routing: configurable seed

This is the fifth version of the mpath seed series.

This patch series adds ability for a user to assign seed value
to multipath route hashes.

- patch was splited to patch series
- remove CONFIG_IP_ROUTE_MULTIPATH define from flow_multipath_hash_from_keys(),
