The specification for the configuration layout for block devices
should be its own subsection as for all other devices and not be
hidden beneath "Feature bits".
The normative sections for device operation should appear under

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.

Patch sent to list (and applied by Rusty in
commit fffcbe327c69e510239fff5627034aa2ab4b2d84
pci: switch from subsystem id to device id

The result is wrong for transitional devices:
Adding 0xfff works for for net+block only;
for transitional pci devices there is no fixed scheme:

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.

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

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.

1) Instead of using N-1 everywhere, use N, and start receiveq etc at 1.
This is less C like, but less confusing in english.
2) Weaken requirements for automatic steering to SHOULD, as otherwise
we're insisting device record all flows forever.
3) Receive buffers must be able to hold data, so must be > header.
