I don't understand it. RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS driver
flag means that driver asks ethdev layer to autofill per-queue
*xstats* (generate names and put values) using per-queue basic
statistics.
Drivers do no set the flag if provide per-queue xstats itself
(to avoid duplication) or do not fill in per-queue basic
xstats (to avoid meaningless/misleading zeros in xstats).
So, absence of the flag does not mean that per-queue basic
statistics are not filled in and should be used as the
guard to include corresponding values in telemetry.
