[net-next RFC PATCH 0/7] multiqueue support for tun/tap
As multi-queue nics were commonly used for high-end servers,
current single queue based tap can not satisfy the
requirement of scaling guest network performance as the

implements multiple queue support in tun/tap.
In order to take advantages of this, a multi-queue capable
driver and qemu were also needed. I just rebase the latest
