Subject:   [Bug 227044] Add support for Intel 9260 and 5165 (iwm) wireless devices

Hi together,
 
I playing around with FreeBSD since around 6 months on a secondary system and like now to run FreeBSD on my primary notebook, whose has the Intel Wireless AC 9260.

root@NilsJ-TP:/ # pciconf -lv
none7@pci0:5:0:0:
    class=0x028000 card=0x00148086 chip=0x25268086 rev=0x29 hdr=0x00
    vendor = 'Intel Corporation'
    device = 'Wireless-AC 9260'
    class = network

After some research I recognized the [Bug 227044](https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227044) and because I've experience in programming, I though I will try to face this issue.

On GitHub I found some changesets in the iwm whose already solved the same task for other 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)

After I've repeated all the changes whose have been done for the 8265 and implemented them similar for the 9260 (because I read they are compatible) I tried to compile the driver as module.
root@NilsJ-TP:/usr/src/sys/modules/iwmfw/iwm9260fw # make

But the make scripts needs a *.fw.uu file... whose is called a firmware?
Could anybody please explain me what kind of file this *.fw.uu is?
Is this really a firmware for the wireless chip?
Could I easily copy the /usr/src/sys/contrib/dev/iwm/iwm-8265-22.fw.uu and use it for the 9260?

Many thanks in advance!
Regards, Nil
