That was merely a suggestion.  My general meaning was "small driver is 
easier to get into the kernel and into the field."

That's one of a gazillion checklist items that a new driver has to pass 
through.  You know how it works for new drivers.

"it looks better than our last try" and "it looks better than that ugly 
driver over there" does not grant you a free pass on review.

I'm not asking for perfection, just something other than

* e1000 gets feedback
* Intel disappears for months
* Intel reappears with e1000 rewrite
* Intel fights tooth and nail when the driver is not accepted verboten

And specifically I worry that three years down the road we will reach 
the same point again, when e1000new is even more complex.

Will Intel shrug its shoulders and decide its time for another rewrite?

Is this is the attitude, what's the point of even posting the driver for 
review?  Intel posted e1000new on June 29.  Feedback was then posted. 
Ten days later, without a single revision, Intel declares its own driver 
clean and working and good enough for merging as-is.
