mask_bits:
Relevant only when MSI is enabled and used for interrupts generated by the 
root port. For each Mask bit that is set, the PCI Express port is prohibited 
from sending the associated message. When only one message is allocated to 
the root port by software, only mask bit 0 is relevant and used by hardware.
