device_identification_number:
Device ID values vary from function to function. Bits
15:8 are equal to 0x0E.
Type: CFG PortID: N/A
Bus: 0 Device: 4Function:0-7
Offset: 0x4
Bit Attr Default Description
15:11 RV - Reserved.
10:10 RW 0x0
intx_interrupt_disable:
Controls the ability of Intel® Quick Data DMA to generate legacy INTx
interrupt (when legacy INTx mode is enabled).
1: Legacy Interrupt message generation is disabled
0: Legacy Interrupt message generation is enabled
If this bit transitions from 1->0 when a previous Assert_INTx message was
sent but no corresponding Deassert_INTx message sent yet, a
Deassert_INTx message is sent on this bit transition
9:9 RO 0x0
fast_back_to_back_enable:
Not applicable to PCI Express and is hardwired to 0
8:8 RO 0x0
serre:
This bit has no impact on error reporting from Intel® Quick Data DMA.
