Edk2 commit 8a45f80eda ("MdeModulePkg: Make HII configuration settings
available to OS runtime") implements the optional UEFI feature described
in "31.2.11.1 OS Runtime Utilization" in UEFI v2.6.
While this feature might show benefits down the road even in QEMU virtual
machines, at the moment it only presents drawbacks:
- it increases the EfiRuntimeServicesData footprint,
- it triggers HII compatibility problems between edk2 and external drivers
unconditionally, even if the end-user is not interested in HII and/or in
configuring said drivers (see
<https://www.redhat.com/archives/vfio-users/2016-March/msg00153.html>
and <http://thread.gmane.org/gmane.comp.bios.edk2.devel/9894> for an
example).
While the feature was being introduced, popular demand for a controlling
Feature PCD rose (see
<http://thread.gmane.org/gmane.comp.bios.edk2.devel/7626>), which is why
we can set it now to FALSE.

This driver implements the VIRTIO_DEVICE_PROTOCOL for non-transitional PCI
devices, based on the virtio-1.0 specification (csprd05). Non-transitional
means that it only binds QEMU's virtio-xxx-pci devices that receive the
",disable-legacy=on,disable-modern=off" properties on the QEMU command
line. These devices have distinct PCI Device IDs from those that are bound
by VirtioPciDeviceDxe.
The central abstraction of this driver is the VIRTIO_1_0_CONFIG type. It
is practically a "fat pointer" to a register block. The pointed-to
register block
- may or may not exist (the latter being mostly useful for virtio-1.0
devices that have no device-specific registers),
- lives in one of the device's BARs,
- lives in an IO or MMIO BAR,
- lives at an offset relative to the BAR start,
- has its size also maintained.
Such VIRTIO_1_0_CONFIG "fat pointers" (i.e., the locations of the register
blocks) are parsed from vendor capabilities that reside in the device's
standard PCI capabilities list (in PCI config space).

In virtio-0.9.5, the size of the virtio-net packet header depends on
whether the VIRTIO_NET_F_MRG_RXBUF feature is negotiated -- the
"num_buffers" field is only appended to the header if the feature is
negotiated.
Since we never negotiate this feature, VirtioNetDxe never allocates room
for the "num_buffers" field.
With virtio-1.0, the "num_buffers" field is always there (although it
doesn't carry useful information without VIRTIO_NET_F_MRG_RXBUF). Adapt
the buffers that depend on the virtio-net header size (otherwise we have
skewed / truncated packets).

The virtio-1.0 spec widens the Features bitmap to 64 bits. Modify the
declarations of the GetDeviceFeatures() and SetGuestFeatures() protocol
member functions accordingly.
Normally, a protocol cannot be changed in incompatible ways if the GUID
stays the same; however, we've always been extremely clear that
VIRTIO_DEVICE_PROTOCOL is internal to edk2. See for example the top of
"OvmfPkg/Include/Protocol/VirtioDevice.h".
In this patch, all producers and consumers of the GetDeviceFeatures() and
SetGuestFeatures() protocol members are updated.
The drivers that currently produce these members are "legacy" drivers (in
virtio-1.0 terminology), and they cannot (and will not) handle feature
bits above BIT31. Therefore their conversion is only for compatibility
with the modified protocol interface. The consumers will be responsible
for checking the VIRTIO_DEVICE_PROTOCOL.Revision field, and for not
passing feature bits that these backends cannot handle.
The VirtioMmioGetDeviceFeatures() implementation stores the result of an
MmioRead32() call with normal assignment, so it needs no change beyond
adapting its prototype.
