Hi,

This is v11 of the server side changes to enable vfio-user in QEMU.

Thank you for reviewing and sharing your feedback for the previous
revision. We have addressed your comments in this revision.

We made the following changes in this series:
[PATCH v11 13/14] vfio-user: handle device interrupts
  - Added msi_set_irq_state() and msix_set_irq_state() to mask
    and unmask individual MSI(x) vectors
  - Implement callbacks to handle the MASK/UNMASK actions
    initiated by SET_IRQS message
  - vfu_object_set_bus_irq() sets the maximum number of IRQS
    to max BDF. This only affects devices using INTx - allows
    multiple devices to use INTx

Thank you very much!
