You can't have two r8168 modules installed at the same time. Use either
the in-kernel one or thebinary driver from Realtek, that's what the ebuild
is checking for. For the 8168 firmware, install linux-firmware.

% qlist linux-firmware | grep 8168

[gentoo-user] net-misc/r8168 build issue

[Hasan Ç .]

Hi All,

This is a known problem kernel uses r8169 ethernet firmware for r8168 chips
and causes connectivity issues.Thanks gentoo there is a r8168 package in
net-misc but i encountered a problem.

-CONFIG_CHECK="!R8169"
-ERROR_R8169="${P} requires Realtek 8169 PCI Gigabit Ethernet adapter
(CONFIG_R8169) to be DISABLED"

emerge --ask net-misc/r8168


* Messages for package net-misc/r8168-8.045.08:
 *   r8168-8.045.08 requires Realtek 8169 PCI Gigabit Ethernet adapter

It seems not allow to build r8168 if kernel compiled with r8169 module.Do
we need to re-compile kernel without r8169?
After i disabled r8169 in /usr/src/linux-$(uname -r)/*.config* manually,
build works.

#CONFIG_R8169=m


 emerge --ask net-misc/r8168

It seems stable but i don't know why it is restricted for r8169 enabled
