SubjectRe: [PATCH v15 00/17] Provide a zero-copy method on KVM virtio-net.

1) Please use kernel-doc style comments to document structure

2) The idea to key off of skb->dev in skb_release_data() is
fundamentally flawed since many actions can change skb->dev on you,
which will end up causing a leak of your external data areas.
