Hi Qiaobin,
This patch: http://patchwork.dpdk.org/patch/46105/ covers the bug. Honnappa
suggested a fix that would work well for the lock free implementation as well.

In current implementation of rte_hash_iterate(), it
tries to obtain the lock after the while loop. However,
this may lead to a bug. Notice the following racing condition:
1. The while loop above finishes because it finds
a not empty slot. But it does so without a lock.
2. Then we get the lock.
