David, 
Sure, I understand.

Please let me recap my last mail:

1)  I'll replace my statically-allocated per-connection "send/recv bufs" with
dynamically ones, so no buf is used when there is no traffic.

2) Another kind of bufs i.e., the  multi-page "VMBus send/recv ringbuffer", is
a must IMO due to the host side's design of the feature: every connection needs
its own ringbuffer, which takes several pages (2~3 pages at least. And, 5 pages
should suffice for good performance). The ringbuffer can be accessed by the
host at any time, so IMO the pages can't be swappable.

I understand net-next is closed now. I'm going to post the next version
after 4.7-rc1 is out in several weeks.

If you could give me some suggestions, I would be definitely happy to take.

Thanks!
