Next Capability (NEXT) — RO. Value of 00h indicates the end of the list.
Capability ID (CID) — RO. Indicates the linked list item is a Message Signaled
Interrupt Register.
Reserved
64-bit Capable (CID) — RO. Set to 1 to indicate that the Gb LAN Controller is capable of
generating 64-bit message addresses.
Multiple Message Enable (MME) — RO. Returns 000b to indicate that the Gb LAN
controller only supports a single message.
Multiple Message Capable (MMC) — RO. The Gb LAN controller does not support
multiple messages.
MSI Enable (MSIE) — R/W.
0 = MSI generation is disabled.
1 = The Gb LAN controller will generate MSI for interrupt assertion instead of INTx
Message Address Low (MADDL) — R/W. This field is written by the system to
indicate the lower 32 bits of the address to use for the MSI memory write transaction.
The lower two bits will always return 0 regardless of the write operation.
