Install r8152 module driver

VIM3
1

It happens that I’d need a second ethernet port. So I bought an usb RTL8152 Fast Ethernet Adapter.
But it seems that in the image I built from Fenix some days ago for Vim3 board that driver is not available:
lsmod | grep r8152 returns nothing and I don’t see any network interface added.

Building the sources downloaded from Realtek returns an error:

Seeking for advices
Thanks

Seems irqflags_debug_arm64.h is missing, can you copy it from linux source code to the board and try again?

Once placed the missing header file I was able to build r8152.ko

> modinfo ./r8152.ko
filename:       /home/khadas/tools/r8152-2.13.0/./r8152.ko
version:        v2.13.0 (2020/04/20)
license:        GPL
description:    Realtek RTL8152/RTL8153 Based USB Ethernet Adapters
author:         Realtek nic sw <nic_swsd@realtek.com>
srcversion:     B118870984E2E7F4366524E
...

Then I ran ‘sudo make install’ getting the following error:

khadas@Khadas:~/tools/r8152-2.13.0$ sudo make install
find: ‘/lib/modules/4.9.224/kernel/drivers/net/usb’: No such file or directory
make -C /lib/modules/4.9.224/build M=/home/khadas/tools/r8152-2.13.0 INSTALL_MOD_DIR=kernel/drivers/net/usb modules_install
make[1]: Entering directory '/usr/src/linux-headers-4.9.224'

modprobe r8152
modprobe: FATAL: Module r8152 not found in directory /lib/modules/4.9.224
make: *** [Makefile:42: install] Error 1

Do I have to rebuild the kernel including the missing module?

wait,
running ‘sudo depmod -a’ fixed it

Yes, it works!
I successfully created a new network interface eth1:

khadas@Khadas:~/tools/r8152-2.13.0$ ifconfig
