# notes to future devs:
# this query does not use the slave_of field in device_port table to group
# ports because what we actually want is total b/w between devices on all
# links, regardless of whether those links are in an aggregate.
# PG 8.4 does not have sorting within an aggregate so we cannot ensure that
# left and right ports and names correspond within arrays. this is why the
# right ports are the left's remote_ports (and right_descr should be ignored)
