Just taking the code base an example,
I think, number of line won't be a concern for upstreaming > 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 I think, key piece would be split the code as reusable library(like mem file)and leverage existing libraries like eal trace. DPDK standardized the new library addition process without doing a lot of throw away code.
