This series implements the eventdev ABI changes required by the DLB and DLB2 PMDs. This ABI change was announced in the 20.08 release notes [1]. This patch was initially part of the V1 DLB PMD patchset.
The DLB hardware does not conform exactly to the eventdev interface. 1) It has a limit on the number of queues that may be linked to a port. 2) Some ports are further restricted to a maximum of 1 linked queue. 3) It does not (currently) have the ability to carry the flow_id as part of the event (QE) payload. Due to the above, we would like to propose the following enhancements. 1) Add new fields to the rte_event_dev_info struct. These fields allow the device to advertise its capabilities so that applications can take the appropriate actions based on those capabilities. 2) Add a new field to the rte_event_dev_config struct. This field allows the application to specify how many of its ports are limited to a single link, or will be used in single link mode. 3) Replace the dedicated implicit_release_disabled field with a bit field of explicit port capabilities. The implicit_release_disable functionality is assigned to one bit, and a port-is-single-link-only attribute is assigned to another, with the remaining bits available for future assignment. Note that it was requested that we split this app/test changes out from the eventdev ABI changes. As a result, neither of these patches will bujild without the other also being applied.
