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.

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.
