--- Comment #1 from Bjoern A. Zeeb <bz@FreeBSD.org> ---
Firmware is installing the tunable by default for select chipset generations; 
you would have a file in
/boot/loader.conf.d/
matching your chipset generation name.conf

If you cannot override this in loader.conf then I'd argue that our loader
include path handling is done in the wrong place and that would unfortunate.  I
hadn't actually checked this.  Aha!

loader.conf(5) says:

     loader_conf_dirs
                   Space separated list of directories to process for
                   configuration files.  The lua-based loader will process
                   files with a ".conf" suffix that are placed in these
                   directories.  Files found here are processed after the ones
                   listed in loader_conf_files but before the ones found in
                   local_loader_conf_files.

So you would need to set
compat.linuxkpi.80211.hw_crypto=0
in /boot/loader.conf.local .

Let me know if this works.
