[RFC PATCH net 0/3] virtio-net: allow usage of small vrings
At the moment, if a virtio network device uses vrings with less than
MAX_SKB_FRAGS + 2 entries, the device won't be functional.
The following condition vq->num_free >= 2 + MAX_SKB_FRAGS will always
evaluate to false, leading to TX timeouts.
This patchset attempts this fix this bug, and to allow small rings down
to 4 entries.
The first patch introduces a new mechanism in virtio core -
