You shouldn't use firmwares from github or anywhere else except from
the two official places where we release it:
Mainline (but slow to get updated):
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-7260-17.ucode
Our official public tree:
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-7260-17.ucode
And, of course, your distro may distribute these in an official package
as well, but it's good to check the versions to be sure you're running
the latest one we released.
