The port management change event can replace smp_snoop. If the capability bit for this event is set in dev-caps, the event is used (by the driver setting the PORT_MNG_CHG_EVENT bit in the async event mask in the MAP_EQ fw command). In this case, when the driver passes incoming SMP PORT_INFO SET mads to the FW, the FW generates port management change events to signal any changes to the driver. If the FW generates these events, smp_snoop shouldn't be invoked in ib_process_mad(), or duplicate events will occur (once from the FW-generated event, and once from smp_snoop). In the case where the FW does not generate port management change events smp_snoop needs to be invoked to create these events. The flow in smp_snoop has been modified to make use of the same procedures as in the fw-generated-event event case to generate the port management events (LID change, Client-rereg, Pkey change, and/or GID change). Port management change event handling required changing the mlx4_ib_event and mlx4_dispatch_event prototypes; the "param" argument (last argument) had to be changed to unsigned long in order to accomodate passing the EQE pointer. We also needed to move the definition of struct mlx4_eqe from net/mlx4.h to file device.h -- to make it available to the IB driver, to handle port management change events.
