Expansion Interface Neighbor Query Test (#237)
This test is non-destructive. The Expansion Interface Neighbor Query Test is a
request to an EI circuit pack to determine if it has established communication
with the EI or Switch Node Interface circuit pack on the opposite end of the fiber.
For EI-EI fiber links, this test is run on both EI circuit pack endpoints of the fiber
link.
