    IB/mlx4: Miscellaneous adjustments for SR-IOV IB support · 992e8e6e
    Jack Morgenstein authored
    1. Allow only master to change node description.
    2. Prevent AH leakage in send mads.
    3. Take device part number from PCI structure, so that guests see the
       VF part number (and not the PF part number).
    4. Place the device revision ID into caps structure at startup.
    5. SET_PORT in update_gids_task needs to go through wrapper on master.
    6. In mlx4_ib_event(), PORT_MGMT_EVENT needs be handled in a work
       queue on the master, since it propagates events to slaves using
       GEN_EQE.
    7. Do not support FMR on slaves.
    8. Add spinlock to slave_event(), since it is called both in interrupt
       context and in process context (due to 6 above, and also if
       smp_snoop is used).  This fix was found and implemented by Saeed
