2014-06-05pci: switch from subsystem id to device idrusty
Switch virtio pci to use standard device id instead of using the subsystem id. Unfortunately, there's no system to the way KVM allocated device IDs to virtio devices, we'll just have to specify these using a table, and use a new range for future devices. For existing devices this results in two possible IDs that all drivers will need to match. Unfortunate, but the cost is small. As a nice side effect, this allows us to make non-transitional devices use IDs 0x40 and up, this reduces even further the chance that a non transitional device will match legacy drivers. And, it's probably a good idea to allow drivers to match specific subsystem IDs if they want to, so relax requirement for drivers to match all subsystem/vendor ID configurations, but allow them to do so. To avoid confusion, say "PCI Device ID" and "PCI Subsystem ID" everywhere, prefix "PCI" for other standard registers, for consistency. VIRTIO-102 Note: issue reporter suggested 0x10XX where XX is the virtio device ID. This would conflict with legacy devices, which seem to have used 7 IDs in the range 0x1000 to 0x103f without any system. Let's use a new range 0x1040 to 0x107f for non-transitional devices, and add a table documenting the transitional IDs used by in practice.

2014-06-05pci: set ISR bit on config change with MSI-Xrusty
config changes are slow path anyway, so we can as well set ISR bit to help drivers detect changes. This allows sharing config interrupts which is what issue reporter seems to ask for.

2014-05-07net: fix device conformance sectionscornelia.huck
For the network device, we had two device normative sections both called "setting up receive buffers", neither of which was referenced in the conformance section. Let's rename the second one to "processing of packets" which seems to better match the actual contents and reference both of them from the conformance statement for network devices. Resolves VIRTIO-97. Agreed on the 2014/05/06 TC meeting.
