This patch glues them all together and makes sure we
notify whenever we don't have enough buffers to receive
a max-sized packet, and adds the feature bit.

Hi guys,
I was looking around at virtio over PCI stuff and noticed you had
started some work on a driver. The last I can find via google is v2 from
mid last year, is that as far as it got?

All,
I have been looking at one of the TODO items in the Linux Hyper-V drivers.
Specifically the one that says;
- remove RingBuffer.c to use in-kernel ringbuffer functions instead.
I spend some time figuring out the ring buffer capability inside of the Linux
Kernel to see if we
Interesting. Since the feature in question is billed first of all a
performance optimization...
By whom? Although I see some improved performance, I think its real
benefit is improving memory utilization on the guest. Instead of using
75K for an ARP packet, mergeable RX buffers only uses 4K.
