Ok. How does the port inform the SM that it has a "preferred" LID?

Using the first IP address we can find was a quick-and-dirty way to pick a LID that would probably be unique among different hosts.

Actually mthca had nothing to do with the LID assignment. It was done by the MAD layer in device-independent code before it starts processing MADs. This means it always happens, since the port cannot possibly be active without processing SMPs.

I guess it depends on whether supporting applications that want to do this becomes important or not.
