Capability Version (capability_version):
PCI Express Capability is Compliant with Version 1.0 of the PCI Express 
Spec.
Note:
This capability structure is not compliant with Versions beyond 1.0, since 
they require additional capability registers to be reserved. The only purpose 
for this capability structure is to make enhanced configuration space 
available. Minimizing the size of this structure is accomplished by reporting 
version 1.0 compliancy and reporting that this is an integrated root port 
device. As such, only three Dwords of configuration space are required for 
this structure.
