Would probably be good to take care of the storm threshold if you haven't,
set it to 0
and you disable the check, that's what we do internally. As for the queues
and number
of descriptors, that's kind of up to you, different work loads and
environments work best
with different setups.

Hopefully, when you get rid of the rx ring setup failure you will get
things working.
