Yes, I know you did. Sorry. I should stop throwing such comments around.

I have a somewhat newer laptop than Borislav. But mine is also a Lenovo
Thinkpad, so that might be a thing. My system is a Lenovo Thinkpad X1
Carbon Gen4, which is a Skylake generation laptop. lspci output as
configured in v4.9:

Attaching the .config. The laptop is running Debian sid, which is more
or less "stretch" now. But I usually build my kernels on a Debian
stable ("jessie") system if that matters.
As for whether it works or not, I must admit that I haven't tested.
Wired ethernet is not something I use on a daily basis on this laptop.
Will test it when I find time, but sending this now so you have
something to start working with.
Thanks
Bjørn
