[PATCH RFC 0/3] virtio and vhost-net capacity handling

OK, here's a new attempt to use the new capacity api.  I also added more
comments to clarify the logic.  Hope this is more readable.  Let me know

This is on top of the patches applied by Rusty.

Note: there are now actually 2 calls to fee_old_xmit_skbs on
data path so instead of passing flag '2' to the
second one I thought we can just make each call free up
at least 1 skb. This will work and even might be a bit faster (less
branches), but in the end I discarded this idea as too fragile (relies
on two calls on data path to function properly).

Warning: untested. Posting now to give people chance to
comment on the API.

Michael S. Tsirkin (3):
  virtio_ring: add capacity check API
  virtio_net: fix tx capacity checks using new API
  virtio_net: limit xmit polling
