[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.

* Messages for package net-misc/r8168-8.045.08:

 *   r8168-8.045.08 requires Realtek 8169 PCI Gigabit Ethernet adapter (CONFIG_R8169) to be DISABLED

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

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

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.
