[dpdk-dev] Release candidate 20.05-rc2 ABI

[Ray Kinsella <mdr@ashroe.eu>]

Folks, 

Few ABI observations based on the 20.05-rc2,
(please correct me if I am wrong)

1. rte_ring.h - struct rte_ring

Changes to the structure of rte_ring throws up a whole bunch of false positives that 
have been suppressed in libabigail.ignore. It is not used by end applications 
and should not be exposed in public headers. 

Suggest that in the v20.11 timeframe we use the opportunity to use opaque pointers 
in librte_efd, librte_hash, librte_pmd_ring, librte_ring, librte_pdump to make this
issue go away permanently. 

2. rte_cryptodev_pmd.h - struct rte_cryptodev_ops

Similarly, changes to the structure of rte_cryptodev_ops are causing false 
positives, also suppressed in libabigail.ignore. It is not used by end applications 
and should not be exposed in public headers. 

3. rte_bbdev.h - struct rte_bbdev_driver_info

Similarly, changes to the structure rte_bbdev are causing false 
positives, also suppressed in libabigail.ignore. It is not used by end applications 
and should not be exposed in public headers. 

Thanks,

Ray K
