Add a function to query for the preferred ring buffer size of VMBus
device. This will allow the drivers (eg. UIO) to allocate the most
optimized ring buffer size for devices.

Query the ring buffer size from pre defined table per device
and use that value for allocating the ring buffer for that
device. Keep the size as current default which is 2 MB if
the device doesn't have any preferred ring size.

Hyper-V is adding some "specialty" synthetic devices. Instead of writing
new kernel-level VMBus drivers for these devices, the devices will be
presented to user space via this existing Hyper-V generic UIO driver, so
that a user space driver can handle the device. Since these new synthetic

Common userspace interface for read/write from VMBus ringbuffer.
This implementation is open for use by any userspace driver or
application seeking direct control over VMBus ring buffers.
A significant part of this code is borrowed from DPDK.

Hyper-V is adding multiple low speed "speciality" synthetic devices.
Instead of writing a new kernel-level VMBus driver for each device,
make the devices accessible to user space through UIO-based
uio_hv_generic driver. Each device can then be supported by a user
space driver. This approach optimiz
Remove use of PAGE_SIZE for device ring buffer size calculation, as
there is no dependency on device ring buffer size for linux kernel's
PAGE_SIZE. Use the absolute value of 2 MB instead.

If the network configuration strings are passed as a combination of IPv4

With these changes, the keyfile config generation logic scans through the
