No need to interconnect the two boards.  You can specify which board
to open using the "which" constructor argument.  The problem with that
is that you really don't know which board you're getting.  After
opening it, check the serial_number()

Note that unless you machine has two ECHI controllers (not two ports),
your total aggregate bandwidth between the two boards is limited to
about 32MB/s.
