Subject: [PATCH net-next v2 1/3] vsock/virtio: use skb_frag_*() helpers
Minor fix for virtio: code wanting to access the fields inside an skb
frag should use the skb_frag_*() helpers, instead of accessing the
fields directly. This allows for extensions where the underlying
memory is not a page.
Signed-off-by: Mina Almasry <almasrymina@...gle.com>

v2:
- Also fix skb_frag_off() + skb_frag_size() (David)
- Did not apply the reviewed-by from Stefano since the patch changed
relatively much.
