[ Impact ]

There exist no formal API to do the FCC unlock procedure[1] in the latest version of the modemmanger.

But there is a merged commit[2] that provide this functionality for intel WWAN cards in the upstream project.

Lenovo have several laptops using the Intel WWAN cards, and Lenovo are struggling to give a decent way to run the FCC unlock service without this.

[ Test Plan ]

OEM enablement engineers and Lenovo engineers will help to test if the FCC unlock would work on certain laptops with the help of a custom package[1] provided by Lenovo which contains the FCC unlock script.

[ Where problems could occur ]

This is a completely new feature to support Intel WWAN cards mutal authentication, which does not affect other existing features.

But the feature itself might have bugs and glitches since it is a brand new one and is not widely tested by the laptop vendors, still it is better than nothing.
