Hi Emmanuel,

Thank you for your work on this.

I have just tried building and installing this on FreeBSD 11-current
r302020, and unfortunately it failed.

To be clear, I took the following steps to perform my testing:

   - git clone -b iwm --single-branch https://github.com/evadot/freebsd.git
   - cd freebsd/sys/modules/iwm
   - make
   - sudo cp if_iwm.ko /boot/kernel/
   - cd ../iwmfw
   - make
   - find . -name "*.ko*" -exec sudo cp {} /boot/kernel/ \;
   - reboot

Upon reboot I got a kernel panic after it loaded the module. I took photos
of my screen at the debug console, which you can find at the link below. If
there is a way to get a better output for debugging, please let me know.

I am not sure what you meant when you said I need the latest firmware
(16.XXX) for the driver to work.

Ben
