For proper Dword alignment, software must always write 0b’s to these
two bits. Otherwise, the result is undefined.
System-Specific Message Lower Address
For MSI-X messages, the contents of this field from an MSI-X table
entry specifies the lower portion of the Dword-aligned address for the
memory write transaction.
System-Specific Message Upper Address
System-Specific Message Data
For MSI-X messages, the contents of this field from an MSI-X table
entry specifies the data written during the memory write transaction.
In contrast to message data used for MSI messages, the low-order
message data bits in MSI-X messages are not modified by the
function.
When this bit is set, the function is prohibited from sending a
message using this MSI-X table entry. However, any other MSI-X table
entries programmed with the same vector are still capable of sending
an equivalent message unless they are also masked.
