2014-08-04legacy: consistently use past tensemstsirkin
Paragraph with general description of feature negotiation for legacy devices mixed present and past tense. As rest of legacy sections all use past tense, fix the only instance of the present tense: s/do/did/ for consistency. It might be argued that legacy devices still have these properties so present tense is more appropriate, on the other hand, using the past tense helps stress the fact that current spec does not attempt to fully describe the legacy device/driver behaviour: this text is only here to serve as motivation for the transitional device/driver requirements.

- change link color from green to pinegreen.

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.
