[ovs-dev] [PATCH ovn 0/4] ECMP routes

[Han Zhou]

This patch series supports ECMP routes in OVN, which is useful for
distributing traffic load evenly between gateway nodes. Please see
use cases discussed in "Gateway load balancing - OVN ECMP" in [0].
It is useful for some other scenarios as well, such as routing traffic
to a set of virtual LBs running in OVN overlay networks.
