What version of the kernel is you using? (uname -r)
Please describe the problem in more detail.

4.17.0-kali3-amd64

Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.

The Linux Kernel 4.17.0 does not supported by the driver.

Tengo el mismo problema, soy desarrollador, como podria aportar para brindar soporte para la version 4.17.0 ?
Saludos.

there is a chance that it will work in the future..?

This seems to be an Ubuntu 18.04 problem and not proper 4.17 kernel. Im facing same issue and my laptop runs Ubuntu 18.04 with 4.15 kernel. Firts im try with master branch and compile process was ok but system freeze like decribing in Issue # 16. Then im try with kernel4.15 branch but im get compile errors "/include/linux/kernel.h:6:10: fatal error: stdarg.h: No such file or directory
#include <stdarg.h>"

I'm on 18.04 too. Same problem. Is there a work around or fix for this problem?
