Description

Currently a router is not automatically discovered. The discovery protocol always runs on the destination bypassing the router all together. In order to work with Health, a router needs to be discovered. This paves the way for LNet health logic to other avoid unhealthy router interfaces. Also if multiple interfaces are on the same network, they all can be used to increase performance with minimal configuration.
