If data buffers decoupling from the rte_mbuf is not available (hugetlbfs is not
available)copy the newly received data into the memory buffer we allocate and
build the "packet" object from this buffer. This will allow us returning the
rte_mbuf immediately which would solve the same issue the "decoupling" is solving
when hugetlbfs is available.
The implementation is simplistic (no preallocation, packet data cache alignment, etc.).
