Capability ID – 1 Byte, Offset 0xA0, (RO) – This field equals 0x10 indicating that the linked list item
as being the PCIe Capabilities Registers.
Next Pointer – 1 Byte, Offset 0xA1, (RO) – Offset to the next capability item in the capability list. A
0x00 value indicates that it is the last item in the capability-linked list.
PCIe CAP – 2 Byte, Offset 0xA2, (RO) – The PCIe Capabilities register identifies PCIe device type and
associated capabilities. This is a read-only register identical to all functions.
