Which restriction do you mean? For the ring layout optimization, this
is the core idea. For the single segment mbuf, this is what all other
PMDs assume for fastest rx/tx path.
With all vhost and virtio optimizations, it could achieve approximately
3~4 times performance improvement(depending on the workload).
Do you mean the indirect feature support or additional optimization not
submitted? Would review your patch this week.
