Port Number (PN):
This field specifies the port number associated with this
element with respect to the component that contains this
element.
Value of 00 h indicates to configuration software that this is the
default egress port.
Component ID (CID):
Identifies the physical component that contains this Root
Complex Element.
This value is a mirror of the value in the Component ID field of
all elements in this component. The value only needs to be
written in one of the mirrored fields and it will be reflected
everywhere that it is mirrored.
Number of Link Entries (NLE):
Indicates the number of link entries following the Element Self
