When snooping a PortInfo MAD, its client_reregister bit is checked. If the bit is ON then a CLIENT_REREGISTER event is dispatched, otherwise a LID_CHANGE event is dispatched. This way of decision ignores the cases where the MAD changes the LID along with an instruction to reregister (so a necessary LID_CHANGE event won't be dispatched) or the MAD is neither of these (and an unnecessary LID_CHANGE event will be dispatched). This causes problems at least with IPoIB, which will do a "light" flush on reregister, rather than the "heavy" flush required due to a LID change. Fix this by dispatching a CLIENT_REREGISTER event if the client_reregister bit is set, but also compare the LID in the MAD to the current LID. If and only if they are not identical then a LID_CHANGE event is dispatched.
