PME Support (PMES)
This field indicates the power states in which this device may
indicate PME wake via PCI Express messaging. D0, D3hot &
D3cold. This device is not required to do anything to support
D3hot & D3cold, it simply must report that those states are
supported. Refer to the latest PCI Power Management
Specification for encoding explanation and other power
management details.

Pointer to Next Capability (PNC)
This contains a pointer to the next item in the capabilities list. If
MSICH (CAPL[0] @ 7Fh) is 0, then the next item in the
capabilities list is the Message Signaled Interrupts (MSI)
capability at 90h. If MSICH (CAPL[0] @ 7Fh) is 1, then the next
item in the capabilities list is the PCI Express capability at A0h.
