[openib-general] [PATCH 2/4] mthca: forward QP COMM_EST and PATH_MIG events to cm_handler

[Sean Hefty]

Forwards communication established and path migration events on a
QP for dispatching to the CM event handler.

I couldn't locate where asynchronous QP events were handled in 
the ipath driver.  If a lower level driver does not dispatch these
events, then connections over that device must wait until an RTU
is received during connection establishment.
