Hi Xiaolong,

Is rte_vdpa_get_device_num() an public API? (It should be since it will be used
in an application in next patch.)

If so, header needs to be part of API documentation:
1- Update doc/api/doxy-api-index.md to include this header.
2- Update all APIs comments to be an doxygen comment.
3- Add doxygen comment to all data structures.

I can see rte_vdpa.h not documented at all, it is not just this API, so it can
be better to send a new patch to address above items.

Thanks,
ferruh
