failed with error -2 iwlwifi drivers

Installed a new kernel.

Started facing issues with intel wireless drivers iwlwifi with new kernel booted.

Errors are as below:

===============================

After some googling (some people use the word RnD ;), what an abuse ) ,figured out that one need to install firmware package separately.

So,

# dnf install    iwl7260-firmware.noarch -y

and it fixed the issue :)
