The atl1 driver is currently marked EXPERIMENTAL, because a few

Patch 1/2 Creates the kconfig option CONFIG_ATL1_EXPERIMENTAL, and
removes the EXPERIMENTAL designation from CONFIG_ATL1
Patch 2/2 Wraps some currently-disabled features in #ifdef
CONFIG_ATL1_EXPERIMENTAL, so developers and testers can play with
these features more easily, and distributions will still get a fast,
stable driver with existing .config files.
We'll also be using this to wrap around various new features we'll be
experimenting with in coming months. Instead of using a half dozen
different kconfig options for each of them, like some drivers do,
we'll just use this, and make sure things are safe for everyone before
we take them out of the experimental wrapper.
Well, I haven't received patch #2 yet, but in general a runtime switch
(module option?) is greatly preferred.

Okay, I'll think about how we want to parameterize this. I don't want users
expecting development options to be around forever. I'll resubmit something
once I have more of these experimental features ready to submit.
