Hi Roland,
Is there a reason why the LID_CHANGE event is happening even if the LID did not
change?

Change the mthca snoop of MADs that set PortInfo to check if the SM
has set the client reregister bit, and if it has, generate a client
reregister event. If the bit is not set, just generate a LID change
event as usual.
