Thanks, David.
The ABI issue is the name of 'rte_mbuf_ext_shared_info::refcnt_atomic' changed to 'rte_mbuf_ext_shared_info::refcnt' at rte_mbuf_core.h.
I made this change just to simplify the name of the variable.

Revert the 'rte_mbuf_ext_shared_info::refcnt' to refcnt_atomic can fix this issue.
I will update it in v2.

Thanks,
Phil
