This driver should only be used for devices not yet supported by the in- kernel driver r8169. Please see the README.Debian for instructions how to report bugs against r8169 that made it necessary to use r8168-dkms. . Installation of the r8168-dkms package will disable the in-kernel r8169 module. To re-enable r8169, the r8168-dkms package must be purged. . This package provides the dkms source code for the r8168 kernel modules. Kernel source or headers are required to compile these modules.
