Add RFS support to virtio network device. Add a new feature flag VIRTIO_NET_F_RFS for this feature, a new configuration field max_virtqueue_pairs to detect supported number of virtqueues as well as a new command VIRTIO_NET_CTRL_RFS to program packet steering for unidirectional protocols. --- Changes from v4: - address Jason's comments - have configuration specify the number of VQ pairs and

The idea of the VIRTIO_BALLOON_F_MUST_TELL_HOST feature is to let drivers skip usage of the deflate queue when leaking the balloon ("silent deflation"). Guests may benefit from silent deflate by aggressively inflating the balloon; they know that they will be able to use ballooned pages without issuing a (blocking) request to the device. The problem is that this feature is a
