# Run opareport -o errors with topology XML, then:
#   Extract values (including port statistics) for both ports of each link
#   Remove redundant information for each link and combine link port information

# NOTE: opaxmlextract produces the following CSV for each port:
#    3 Link values (CSV 1-3)
#    3 Cable values (CSV 4-6)
#    2 Port values (CSV 7-8)
#    1 Stat value (CSV 9)

# Combine 2 ports for each link onto 1 line, removing redundant Link and Cable values
