tar includes sources, firmware, etc.

I'm still new to FreeBSD, especially developing drivers is new for me...
nevertheless I like to get the "Intel Wireless AC 9260" on my "ThinkPad E490"
running in FreeBSD and tried to follow these changesets in the iwm whose
already solved a similar task for another chipsets:
[Add support for Intel 8265
WiFi](https://github.com/freebsd/freebsd/commit/a06e5178adcde2036444b756a2e996513ec570bd)
[Add support for iwm 3168
cards](https://github.com/freebsd/freebsd/commit/5237c88c1abcac87b47cc12cee1dff7de106d4d0)

But I still stock at the firmware whose I've downloaded and uuencoded but seems
to be not compatible... could anybody follow up this issue? 
My changes, sources, firmware you will find attached, as well as some results.
