Ubuntu – Install atheros e2600 drivers

I have got a laptop on ubuntu 16.04 and I can't configure the ethernet card …
I don't have wifi and ethernet connexion…
I believe that it is a atheros e2600 but I am not sure.

when I type modinfo alx I have this :

If I do lspci -nn I have this:

02:00.0 Network controller [0280]: Inter Corporation Device [8086:24fb] (rev 10)
03:00.0 Ethernet controller [0200]: Qualcomm Atheros Device [1969:e0b1] (rev 10)

I have download linux-firmware_1.127.22_all.deb and installed doing:
sudo dpkg -i linux-firmware____.deb

I have tried this solution as weel:
[Is there any way to install Atheros e2400 drivers?

without success either.

I added :
enter code #define ALX_DEV_ID_E2600 0xe0b1
in reg.h
and :

{ PCI_VDEVICE(ATTANSIC, ALX_DEV_ID_E2600),  .driver_data = ALX_DEV_QUIRK_MSI_INTX_DISABLE_BUG },

in main.c

but when I do

`make -C /lib/modules/$(uname -r)/build M=$(pwd) modules

(when I am in /ubuntu-xenial/drivers/net/ethernet/atheros/alx, is that where I should do it ?)
I don't have any error.
(make entering directory /usr/src/linux-headers-4.4.0-31-generic etc … and then make leaving directory same one)

but when I do :

sudo make -C /lib/modules/$(uname -r)/build M=$(pwd) modules_install

I have an error:
"no such file: bss_file.c:178 sign-file: certs/signing_key.pem no such file or directory".

any Idea ?
