* Released as 3.7.0.
* Added or improved the following capabilities: Designated
Vendor-Specific, Compute eXpress Link, Resizable BARs,
VF Resizable BARs, Link Capabilities 2, Link Status 2.
* On Linux, lspci can show IOMMU groups.
* setpci can be asked to skip bus scan and operate on a device
completely specified by its domain/bus/dev/func address. This
involved major internal cleanup.
* The above feature of setpci uses the pci_get_dev() function,
which obtains a struct pci_dev without doing a bus scan. This was
always possible, but apparently little used, because back-ends
frequently choked when operating on such devices. Fixed a lot
of minor bugs related to this.
* Also, back-ends which do not support domains now correctly fail when
trying to access devices outside domain 0.
* Semantics of pci_fill_info() and pci_dev->known_fields was
underspecified, which lead to inconsistencies between back-ends.
Improved documentation to give a more precise definition and updated
all back-ends to conform to it. Most importantly,
pci_dev->known_fields shows all fields requested over the lifetime
of the pci_dev, but never those which are not supported by the
back-end.
* As usually, updated pci.ids to the current snapshot of the database.
