I apologize for the long copy list. I have tried to include all
known interested parties.

This is a follow-up to a thread started by Andrew a few weeks ago
about what should be merged for 2.6.18. One of the topics he cited
was the ACX100 driver which he has carried in -mm for quite some time.
I have a slightly different (softmac based) version of that driver
in wireless-2.6 which I think is worth merging now.

In the aforementioned thread, some questions were raised about the
legality of the ACX100 driver (i.e. tiacx) code base, but no one
had any specific points other than that it is not 100% "clean room"
derived. Others point-out that this is not strictly a requirement.
The matter dropped without a strong defense from the tiacx team.

I hereby invite the tiacx team to defend their work by making public,
affirmative statements indicating a) how they produced their code; and,
b) that they have the legal right to license it as part of the Linux
kernel under the GPL. As an incentive to this, I have already made
the necessary preparations for this driver to be merged immediately.

This is the softmac-based tiacx that has been in wireless-2.6 for
some time, with the addition of a few patches that akpm had in -mm
which I did not previously have. For easy review, a tarball with
the full driver is available here:

A git pull request follows. I am confident that if the legal status
of this code can be confirmed, it will be merged upstream ASAP.

Comments welcome!
