**ef10_simple** chooses EF10 (SFN7xxx, SFN8xxx, X2xxx) native datapath which
is even more faster then **ef10** but does not support multi-segment
mbufs, disallows multiple mempools and neglects mbuf reference counters.
**ef100** chooses EF100 native datapath which does not support
any offloads except multi-segment mbufs.
