First of all you are absolutely right, this is an implementation extension
and not IB spec definition. I believe that the PKEY change event is also
not defined in the IB spec ..

The motivation for this event is that if one uses GRH he don't put the
actual value in the GRH props, he only supply the index in the GID table
to be used.
I believe that if the openSM will decide to change the GID table, the user
will like to know if the index is now containing a different value ...
