Thanks Thomas. 

Bruce, Ferruh can you comment whether bumping ABI version is required for __rte_experimental API? Arguably the documentation may be interpreted either way : https://doc.dpdk.org/guides-18.08/contributing/versioning.html 

In the specific case of bbdev change in that serie, note that only new operations (for 5GNR signal processing) and related symbols are being added. 
Previous releases included BBDEV API changes without updating ABI version number ( librte_bbdev.so.1). 

Thanks for letting me know, in both cases we may make it more explicit on the versioning page.
