When a device supports MSI, it can generate an interrupt request to the processor by  
writing a predefined data item (a message) to a predefined memory address. The  
reporting of the existence of this capability can be disabled by setting MSICH (CAPL[0]  
@ 7Fh). In that case walking this linked list will skip this capability and instead go  
directly to the PCI PM capability.
