From: Arnd Bergmann <arnd@arndb.de>

There are no known users of this driver as of October 2020, and it will
be removed unless someone turns out to still need it in future releases.

According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, there
have been many public wimax networks, but it appears that these entries
are all stale, after everyone has migrated to LTE or discontinued their
service altogether.

NetworkManager appears to have dropped userspace support in 2015
https://bugzilla.gnome.org/show_bug.cgi?id=747846, the
www.linuxwimax.org
site had already shut down earlier.

WiMax is apparently still being deployed on airport campus networks
("AeroMACS"), but in a frequency band that was not supported by the old
Intel 2400m (used in Sandy Bridge laptops and earlier), which is the
only driver using the kernel's wimax stack.

Move all files into drivers/staging/wimax, including the uapi header
files and documentation, to make it easier to remove it when it gets
to that. Only minimal changes are made to the source files, in order
to make it possible to port patches across the move.

Also remove the MAINTAINERS entry that refers to a broken mailing
list and website.

Is this ok for me to take through the staging tree?  If so, I need an
ack from the networking maintainers.

If not, feel free to send it through the networking tree and add:

Wimax is still pretty common in Africa.  But you have to buy an outdoor
antenae with all the software on it and an ethernet cable into your
house.  I don't know what software the antennaes are using.  Probably
Linux but with an out of tree kernel module is my guess.

Ah, good to know, thanks for the information. I'll include that when
I resend the patch, which I have to do anyway to avoid a small
regression. I did a look at a couple of African ISPs that seemed to
all have discontinued service, but I suppose I should have looked
more carefully.

Right, it seems very unlikely that they would be using the old
Intel drivers, and it's also unlikely that they are updating those
boxes to new kernels. I found a firmware image for Huawei
BM623m, which runs a proprietary kernel module for the wimax
stack on an MT7108 (arm926) phone chip running a
linux-2.6.26.8-rt16 kernel.

Thinking about it now - we want this applied to -next, correct? 
In that case it may be better if we take it. The code is pretty dead
but syzbot and the trivial fix crowd don't know it, so I may slip,
apply something and we'll have a conflict.

I think git will deal with a merge between branches containing
the move vs fix, so it should work either way.

A downside of having the move in net-next would be that
you'd get trivial fixes send to Greg, but him being unable to
apply them to his tree because the code is elsewhere.

If you think it helps, I could prepare a pull request with this one
patch (and probably the bugfix I sent first that triggered it), and
then you can both merge the branch into net-next as well
as staging-next.

If you wouldn't mind branch sounds like the best solution.

+There are no known users of this driver as of October 2020, and it will
+be removed unless someone turns out to still need it in future releases.
+
+According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, there
+have been many public wimax networks, but it appears that these entries
+are all stale, after everyone has migrated to LTE or discontinued their
+service altogether.
+
+NetworkManager appears to have dropped userspace support in 2015
+https://bugzilla.gnome.org/show_bug.cgi?id=747846, the www.linuxwimax.org
+site had already shut down earlier.
+
+WiMax is apparently still being deployed on airport campus networks
+("AeroMACS"), but in a frequency band that was not supported by the old
+Intel 2400m (used in Sandy Bridge laptops and earlier), which is the
+only driver using the kernel's wimax stack.
