The error message isn't really telling much to the user (hint hint) but
I suspect this is by design:

"iwlwifi: remove support for fw older than -17 and -22

FW versions older than -17 for 3160 and 7260 and older than -22 for
newer NICs are not supported anymore. Don't load these versions
and remove code that handles them."

Adding luca.
