The pool initialization is not completed yet (private structure of mbuf pool is
not copied yet, so in this point rte_pktmbuf_data_room_size() is unable to fetch
the valid data room size. Beside this, rte_pktmbuf_data_room_size() returns the
valid value for the mbuf with pinned external buffers after pool initialization is done.
With best regards, Slava
