xen-netback: batch copies for multiple to-guest rx packets
Instead of flushing the copy ops when an packet is complete, complete
packets when their copy ops are done. This improves performance by
reducing the number of grant copy hypercalls.
Latency is still limited by the relatively small size of the copy
batch.
