Hi Vincent,

Thanks for the comments and some quick responses below:

- DPDK Bloom Filter is derived from the libbloom (as shown by the included BSD license), but optimized for performance with various DPDK goodness such as rte_zmalloc, rte_bitmap, rte_jhash, etc. It doesn't seem appropriate to    bring those DPDK specific features into libbloom, which is designed for more generic environments.
- DPDK Bloom Filter is just one very basic mode among other more sophisticated ones in the DPDK Membership Library, which supports a different set of APIs (e.g., bulk lookup, multi-match, etc.) than those supported in libbloom.
- It may make sense to bring some generic (i.e., non DPDK specific) improvements back to libbloom once identified.

Thanks
Yipeng
