This patchset refactors the eventdev API to be more flexible
and capable. In particular, the API is capable of returning an
error value if an invalid device, port or attribute ID is passed
in, which was not possible with the previous APIs.
The implementation of this patchset is based on a v1 patch,
and after some discussion this API was seen as the best solution.
In terms of flexibility, the attribute id allows addition of new
common eventdev layer attributes without breaking ABI or adding
new functions. Note that these attributes are not data-path, and
that PMDs should continue to use the xstats API for reporting any
unique PMD statistics that are available.
Regarding API/ABI compatibility, I have removed the functions from
the .map files - please review the .map file changes for ABI issues
The last patch of this series adds a started attribute to the device,
allowing the application to query if a device is currently running.
