   **efx** chooses libefx-based datapath which supports VLAN insertion
   (full-feature firmware variant only), TSO and multi-segment mbufs.

   **ef10** chooses EF10 (SFN7xxx, SFN8xxx) native datapath which is
   more efficient than libefx-based but has no VLAN insertion and TSO

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