xstats are driver agnostic and have a well-defined naming scheme.
> For example, what if there was a kind of "stats registry" composed of ID and name. It would work similar to xtats except instead of advertising strings only the "get" API would return ID/count pairs. If the application wishes to use the DPDK provided string they can call another API to get the stat string via the ID. These IDs would be well-defined clearly explaining what the count represent. This way the strings for counts will be uniform across drivers and also make it clear to the users what the counts truly represent and the application could obtain stats from any driver in a driver agnostic manner.
I don't understand how adding another indirection (an ID matching a string)
I have the feeling you want a list of possible statistics, right?
