unknow Network controller: Intel Corporation Device 093c (rev 3a)

[Corentin Labbe]

Hello

I have a thinkpad t460s laptop with an unknow network device.
Since the laptop does not have wifi, I suspect it is the wifi card.

The laptop is running Debian bookworm, and I tried to update pci.ids, no more information.

lspci -vx give:

I see no loading problem, nor firmware missing message in dmesg.

According to ifixit teardown images, that came with an 8260 WiFi NIC.

But that doesn't match at all, not even close.

I cannot find any record for WiFi of these numbers, so either the device
is not WiFi or is malfunctioning. You could try to open it up, take a
picture so we can see what the WiFi NIC is, and also maybe re-seat the
NIC while at is, occasionally that fixes such issues.

https://linux-hardware.org/?id=pci:8086-093c-8086-2181

Suggests it to be a "Intel Wireless Gigabit 17265", with no linux driver 
existing for it.
