I do agree that conceptually it makes a lot of sense to encapsulate the
budget like this so drivers don't have to do all this state tracking
themselves. It does appear that drivers are doing different things with
the budget as it is today, though. For instance, the intel drivers seem
to divide the budget over all the enabled RX rings(?); so I'm wondering
if it'll be possible to unify drivers around a more opaque NAPI poll API?

We can come up with APIs which would cater to multi-queue cases.
Bigger question is what is the sensible polling strategy for those,
just dividing the budget seems, hm, crude.
