This seems like we're going down the broadcom model where we have
the b34_legacy, b43, brcm drivers.  We've got three drivers for
broadcom cards and there is some overlap on which hardware they
support.  The first two were developed by the community and the brcm
driver was developed by Broadcom and it's the only one they support.
It was a frustrating experience.  We came very close to dropping the
brcm drivers.

The thing about the brcm drivers was that the Broadcom devs did all
their development in the open.  We knew they had worked hard and
were responsive to bug reports and code criticism.

The kernel history is full of people working hard for years on code
and then having it rejected and not merged.  When it comes to
drivers we often think we'll write a new driver and drop the old one
but it doesn't always happen.  We still have OSS sound drivers from
90s.

It's best to put up a git tree with the new driver as soon as
possible.  I would try get stuff merged into the kernel as soon as
possible.

dan carpenter
