LinkStatus isn't really relevant to Infiniband - disconnected ports essentially don't exist. As we evaluate adding support for additional transports to the system, we may add something like this; that will be determined in the future.

I am reopening this issue after a discussion with Michael. We are going to have a LinkStatus? element for each port, it will have a value of Up or Down depending on if the port was found during the most recent update iteration.

I should clarify my above comment. After a discovery of the network, each port will have a LinkStatus? value of Up. During each subsequent update interval, the value will be changed to Down if we cannot query that port for some reason. This change could indicate a failed network cable, subnet manager, or some other failure.

The alternative to this is to force a network discovery event at regular intervals, which is somewhat of an expensive process compared to polling each port for counters.
