[Tang, Changqing]

One other thing I hope to talk is some fabric query functionalities for normal user,
not only just for root. This is at IB verbs level, not rdma_cm level.

for example, in MPI, process A know the HCA guid on another node. After running for
some time, the switch is restarted for some reason, and the whole fabric is re-configured.

Now process A wants to know if the port lid on another node has changed or not, it knows
the HCA guid,  is there any function to query this ?

I know as root, we can use the mad/umad library to do this kind of query, I want to do
such query in MPI, which is a normal user.
