This helper returns 1 if a call to add_buf will not fail
with -ENOSPC.
This will help callers that do
while(1) {
alloc()
if (add_buf()) {
free();
break;
}
}
This will result in one less alloc/free exercise.

Use the can_add_buf virtqueue operation to test if
there's room to add another buf to the queue.
Saves us one cycle of alloc-add-free if the queue
was full.

This adds support for vhost-net virtio kernel backend.
This is RFC, but works without issues for me.
I got this to build by syncing up some headers in kvm/include/linux,
but it doesn't seem to be working quite right. I

Did you assign ip address in host by any chance? You don't want that.
Nope, just up on the host, no IP:
eth10 Link encap:Ethernet HWaddr 00:17:a4:77:a4:08

I'm in the process of repeating the same experiment with cxgb3
which hopefully should let me turn interrupts off on descriptors
while still reporting completion status.
Ok, I look forward to seeing your work
