Hello,
i just noticed that the new syctl net.ipv4.fib_multipath_hash_policy
with it's default to 0 breaks with the previous behaviour.

I have a numbered leaf-spine underlay for vxlan with ospf. After an
upgrade when running iperf with -N >1 only a single path was used due to
the hasing-policy.

sysctl -w net.ipv4.fib_multipath_hash_policy=1 resolved this.

This probably affects a lot of setups where ecmp is in use, so i wonder
if there should be at least a hint in the docs.

Best regards,
Alex
