Agree, I was planning on another version to address this (I am yet to take a look at your patch addressing the ABI).
The structure visibility definitely needs to be addressed.
For the inline functions, is the plan to convert all the inline functions in DPDK? If yes, I think we need to consider the performance difference. May be consider L3-fwd application, change all the inline functions in its path and run a test?
