You are extending the generic stats. This is not the idea behind xstats.
The xstats are specific to the driver.
Furthermore we should migrate some "not really generic stats" to xstats
in order to keep only the really basic and common stats in rte_eth_stats.
By the way, in order to avoid duplicated code when getting generic stats
through xstats API, we need to change the implementation of
rte_eth_xstats_get() to add generic stats automatically, even if the
driver provide some xstats.
