Basically yes
If you want to avoid all the SM stuff, and are willing to program the
switches directly (a few mads), then I've used schemes like:
Node LID=base + (switch port * constant) (base=0, constant = 1 works)
Then to figure out QP connections, you just use a function of 3
parameters:
my_qp_num

You would also need to walk the ports to active (via MADs) after setting
the LIDs as well as setup the switch forwarding table (LFT).

For one thing, SM needs to try to keep ports at active.
