Could you share the rational for why rte_eventdev_port_data needs to be added?

"rte_eventdev_port_data" is used to hold callbacks registered optionally per event device port and associated callback data.
By adding "rte_eventdev_port_data" to "rte_event_fp_ops", allows to fetch this data for fastpath eventdev inline functions in advance.

It does not look necessary to announce adding new fields.
The ABI compatibility breakage should be covered by this patch:

Marking as superseded.
