Jason Wang 51a81a2118 virtio-net: calculating proper msix vectors on init ... Currently, the default msix vectors for virtio-net-pci is 3 which is obvious not suitable for multiqueue guest, so we depends on the user or management tools to pass a correct vectors parameter. In fact, we can simplifying this by calculating the number of vectors on realize. Consider we have N queues, the number of vectors needed is 2*N + 2 (#queue pairs + plus one config interrupt and control vq). We didn't check whether or not host support control vq because it was added unconditionally by qemu to avoid breaking legacy guests such as Minix.
