It hasn't been mentioned in this thread that the Intel driver is adequate
documentation, because it isn't. (I've read it.)

Part of the problem is that Intel *haven't* disclosed a lot of the
information that's necessary in order to write a driver other than the
one they've written. Much of the information that a driver author
requires is not clearly disclosed in source for another OS' driver, and
again, this is the case with the Intel driver.
Just in case it's not clear, I have on a number of occasions been forced
to reverse-engineer drivers from source, so I can claim to speak on this
topic with some authority. 8)

This actually has almost nothing to do with it; placing the programming
documentation under NDA does almost nothing to preclude a competitor from
either cloning the part or for that matter obtaining the documentation
themselves.
NDA's in this particular space serve a limited set of purposes:
- They constitute engineering damage control; witness Realtek's
unhappiness at Bill's honest commentary on their documented parts.
- They provide a theoretical underwriting for the "intellectual
property" that a company's accounting department likes to think it has.
- They allow a company to control (to some degree) the uses to which its
products are put. This is typically a marketting angle (by forcing a
customer to negotiate, you can force a variety of concessions,
co-deals, etc.).
And in our case, they also serve to stifle otherwise legitimate support
for a product, simply because we don't fit into a category they
understand. Irritating, but difficult to deal with.
