Makes sense. I checked
https://en.wikipedia.org/wiki/List_of_WiMAX_networks, and 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.

Inaky, do you have any additional information about possible
users? If we are sure there are none, then I'd suggest removing
all the wimax code directly, otherwise it could go through
drivers/staging/ for a release or two (and move it back in case
there are users after all). I can send a patch if you like.

I have not

Every now and then I get the occasional message from a student or
researcher asking for support about a production network, but they
have dwindled in the last years.

My vote would be to scrap the whole thing; if there are die hard
users, they can always rise up and move it back from staging.
