The behaviour is logical, but what to do if HW can't do it,
i.e. use the last segment many times. Should it reject
configuration if provided segments are insufficient to fit
MTU packet? How to report the limitation?
(I'm still trying to convince that SCATTER and BUFFER_SPLIT
should be independent).

I dislike the idea to introduce new device operation.
rte_eth_rxconf has reserved space and BUFFER_SPLIT offload will
mean that PMD looks at the split configuration location there.

Above duplication is simply not acceptable, but even if we
factor our shared code into helper function, I still see no
point to introduce new device operation.
