Actually, none of these modes are intended to support HCA scenarios,
they are all only for switches.
Well, they attempt to work on local HCAs if you don't specify a switch
lid to query. So, intended or not, they are already being attempted to
be used in this fashion out in the field.
Not sure what I think of this, is dumping counters on all local HCA
ports really that interesting? Would this be better done by doing
something fancy with nodeGUID so at least all ports on remote HCAs can
be dumped too?
The request came in from one of our partners who wanted it for tracking
performance stats specifically on the local machine.
