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 :

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.

No those modules were not included .
I added the following to the /etc/mkinitcpio.conf
MODULES=(libphy realtek r8169)and done :
# mkinitcpio -Prebooted and the problem is still there.
# dmesg | grep r8169

What if you drop libphy from the MODULES array?
Offline
removed libphy and regenerated the initrd image , rebooted, same result.
Offline
Was libphy included in the initrd as a dependency?
Offline
I don't know.
Is there a command to check that?
Offline
Yes in post #2 but skip that for a moment.
If you unload libphy realtek r8169
modprobe -r r8169
modprobe -r realtek
modprobe -r libphyThen try loading the r8169 module
modprobe r8169If the issue is still present try unloading the three modules then try loading the realtek module before the r8169 module.
Offline
Tried both to not avail.
Also tested the following too :
MODULES=(realtek)
MODULES=(libphy)
MODULES=(libphy realtek)didn't help either.

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.

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.shIt seems to work just fine for now (will update if anything goes south)
# lspci -v

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 .

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).

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
