Hopefully, there would be one or more open source projects using the API. I just did a survey of DPDK an 1/3 of it is never used by any open source project. Hate to see more dead code and special cases created. At least, some example code in examples would help. Something like a simple in memory compressed storage server using a network API (SMB?/SSH?/FTP?)
