It is observed that the throughput of medium number of flows(9-8191) is
worse than low number of flows(1-8) in the EMC NIC2NIC test.
This patch improves it by prefetching EMC entry in advance. In order not to
affect low and high number of flows scenario, an EMC counter is introduced
to prefetch only under the medium number of flows scenario.

dpif-netdev: add EMC entries counter
dpif-netdev: dfc_process performance optimization by prefetching EMC
entry.
