# NAME
# ibdiagpath
#
# DATAMODEL
# Note: all global variables are placed in the array G
#
# FUNCTION
# ibdiagpath traces a path between two LIDs/GUIDs
# and provides information regarding the nodes and ports passed and their health.
# ibdiagpath utilizes device-specific health queries for the different devices on the path.
