Agree that xstats are better but:

* the current checked in version of GVE does not have driver op for xstats

* if driver fills in the q_XXX[] stats then eth_dev_get_xstats_basic will be
  able to use it.

The per queue stats are limited to 256 queues and bloats the info structure,
but until an API breaking change is made to remove them, drivers should support
it.
