Hello folks,

A few days ago I got my hands on a Lenovo ThinkPad X1 Carbon Gen 9. This laptop
ships with an Intel AX210 radio.

Running stable/13 on this machine seems to work fine so far. The only missing
piece is the wireless driver.
I am fully aware of the fact that the current state of the new iwlwifi driver
doesn't support 802.11ac or 802.11ax. I'd be happy with getting 802.11b/g/n
working.

On 2021-11-27 I updated stable/13 and tried to apply the setup script which
is supposed to patch the kernel source to make this new driver work. However,
this operation was unsucessful:

root@x1g9:/usr/src # ./iwlwifi.sh
Script expects to run from src/

The iwlwifi wiki was updated in the meantime with this note:

> 2021-11-28 The driver and firmware went into HEAD (detached from build)

My question: As of today, what is the correct way to get the iwlwifi driver
onto a stable/13 system? As per my understaning, HEAD would correspond to
-CURRENT which would mean that stable/13 doesn't (yet) have these changes. Will
these MFCs show up in the next few days?

Thank you all for your efforts.

Best regards,
