Hi.
I'm looking at implementing rte_event_dev_xstats_by_name() for DSW, and
I have some API-related questions.
Shouldn't rte_event_dev_xstats_by_name_get() return mode and queue/port
id? Otherwise the caller needs to know if the name refers to a device-
or port-level stat, and in case of the latter also the port or queue id.
That information is needed in subsequent rte_event_dev_xstats_get() call.
Also, the API states that the function may return "negative value:
-EINVAL if stat not found, -ENOTSUP if not supported", which is somewhat
misleading, since the return value is of an unsigned type.
Regards,
Mattias
