[SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

Hello everyone ,
I have this Dell Inspiron 5520 laptop , and everything was working fine and smooth till earlier today I upgraded to the latest lts version 5.4.30-1 kernel, the ethernet interface is gone.
Going back to linux-lts-5.4.28-1 and it shows up again.

here is some info I extracted from my box :

#uname -a 
Linux archlinux 5.4.30-1-lts #1 SMP Thu, 02 Apr 2020 14:39:46 +0000 x86_64 GNU/Linux

notice there is no 'Kernel driver in use: r8169' line compared to when I go back to 5.4.28-1


#lsmod |grep r81

notice the 3rd and 4th lines!


any help would be highly appreciated.

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

Is r8169 or libphy included in the initrd?

lsinitcpio /boot/initramfs-linux-lts.img | grep usr/lib/modules/

Edit:
Also the full output of lsmod from under linux-lts 5.4.30-1.

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

No those modules  were not included .

I added the following to the /etc/mkinitcpio.conf

MODULES=(libphy realtek r8169)

and done :

# mkinitcpio -P

rebooted and the problem is still there.

# dmesg | grep r8169
[    1.017188] r8169 0000:07:00.0: can't disable ASPM; OS doesn't have ASPM control

thanks.

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

What if you drop libphy from the MODULES array?

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

removed libphy and regenerated the initrd image , rebooted, same result.

Was libphy included in the initrd as a dependency?

Is there a command to check that?

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

Yes in post #2 but skip that for a moment.
If you unload libphy realtek r8169

modprobe -r r8169
modprobe -r realtek
modprobe -r libphy

Then try loading the r8169 module

modprobe r8169

If the issue is still present try unloading the three modules then try loading the realtek module before the r8169 module.

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

Tried both to not avail.

Also tested the following too :

MODULES=(realtek)
MODULES=(libphy)
MODULES=(libphy realtek)

didn't help either.

[   16.923485] r8169 0000:07:00.0: realtek.ko not loaded, maybe it needs to be added to initramfs?

Was still present even if you unloaded the three modules,  then loaded the realtek module before the r8169 module?

Yes in both cases the output of the dmesg was the same. Thats also the case with the various combinations of the MODULES array above.

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

I couldn't figure out what the problem is , and did not spend much time either. But I ended up with installing the driver provided by the Realtek and it seems to be opensource(or at least parts of it is GPL2+) and last updated 2020/03/11 !

it is mentioned  " FE Ethernet LINUX driver for kernel up to 4.15 " but seems to work under 5.4.30-1.

here is the link to the driver's page.

the installation process was straightforward , just extracted the r8101-1.035.02.tar.bz2  and :

# ./autorun.sh

It seems to work just fine for now (will update if anything goes south)

# lspci -v

I blacklisted all three modules libphy , realtek , r8169 .

# dmesg | grep r81

[   17.853110] r8101 0000:07:00.0 enp7s0: renamed from eth0

Notice the patents.

I am going to test it  for the time being and see what happens when the new LTS kernel upgrade is available.

Thanks for your help loqs I've learned so much from you .

PS:
If you want to investigate the problem any further I will be happy to assist.

PSPS:
There is an AUR package named r8101-dkms , haven't test it yet but worth mentioning since it is DKMS .

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

5.4.30 checks for a dedicated PHY driver to fix an issue with module handling on Android/x86. Seems that for your chip version no dedicated PHY driver exists.
Please check (with r8169 under 5.4.28) for attribute phy_id in sysfs and report the value (supposedly 001cXXXX).

Re: [SOLVED] No ethernet interface after upgrading to linux-lts-5.4.30-1

Thank you behnamgolds as you gave me the solution. Nevertheless, with kernel 6.2.6-arch1-1 it needs an update.

After running ./autorun.sh the following error appears:

In file included from r8101-1.038.02/src/r8101_n.c:75:
r8101-1.038.02/src/r8101_n.c: In function ‘rtl8101_init_one’:
r8101-1.038.02/src/r8101.h:495:57: error: too many arguments to function ‘netif_napi_add’
  495 | #define RTL_NAPI_CONFIG(ndev, priv, function, weight)   netif_napi_add(ndev, &priv->napi, function, weight)

The solution is to delete the parameter weight in the function netif_napi_add in line 495 of the source file src/r8101.h and to change it from

#define RTL_NAPI_CONFIG(ndev, priv, function, weight)   netif_napi_add(ndev, &priv->napi, function, weight)

into

#define RTL_NAPI_CONFIG(ndev, priv, function, weight)   netif_napi_add(ndev, &priv->napi, function)

After deleting the weight parameter, run again sudo ./autorun.sh and the error disappears.

HT goes to Linux source net: drop the weight argument from netif_napi_add
