Hi Jerin,

Thanks for you suggestion and these really are good points!

Although libtpa is currently designed as a libray, I doubt it would suit
well as a new library to DPDK. Just taking the code base an example,
libtpa so far is about 27K lines of code. The TCP part is only about
3K lines of code. All the rest are codes supporting the TCP part, such
as sock tracing, mem file, mem file auto archive, etc. You can look
more from the internals page (or even read the code ;)

Thanks,
Yuanhan Liu
