Hi,

When I run my application DPDK doesn't receive any packets after about 3
minutes.
So I figured out why rte_rx_burst() returned 0 and the reason is
rte_rxmbuf_alloc() failure. rte_rxmbuf_alloc() == NULL.
I printed some statistics and it showed that the prod's head and cons' head
are same.
What does this mean?
And rte_mempool_empty and rte_mempool_full always failed.

Thanks.
