[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
numbers of vcpus increase. So the following series
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
