Refactor the to-guest (rx) path to: 1. Push responses for completed skbs earlier, reducing latency. 2. Reduce the per-queue memory overhead by greatly reducing the maximum number of grant copy ops in each hypercall (from 4352 to 64). Each struct xenvif_queue is now only 44 kB instead of 220 kB. 3. Make the code more maintainable. Signed-off-by: David Vrabel <david.vrabel@citrix.com> [re-based] Signed-off-by: Paul Durrant <paul.durrant@citrix.com> Signed-off-by: David S.
