Re: [libvirt] [PATCH v3 06/15] conf: expand network device callbacks to cover bandwidth updates

Currently the QEMU driver will call directly into the network driver impl to modify network device bandwidth for interfaces with type=network. This introduces a callback system to allow us to decouple the QEMU driver from the network driver. Signed-off-by: Daniel P.
