[libvirt] [PATCH v2 00/12] Multiple TX queue support



Just a rebased version of [1].

Kernel and subsequently QEMU learned multiple transmit queues a while ago. The
feature has a nice advantage, it allows a single guest to transmit multiple
flows of network data using multiple CPUs simultaneously which increase traffic
bandwidth. A lot.

The documentation how to use this is available at [2] or [3].
