Bug Description

1) Ubuntu release that I'm using:
~$ lsb_release -rd
Description: Ubuntu 12.04.3 LTS
Release: 12.04
~$ uname -r
3.8.0-31-generic
2) The problem is in the network card driver that is bundled in the kernel
3) Stable operation of the network interface adapter without errors in the log about link instability
4) When the adapter is enabled to work on a 1Gbps speed it fulls the syslog with the following (MAC address is cleared from the log):

The output of lspci -k is:
44:01:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8169 PCI Gigabit Ethernet Controller (rev 10)
45- Subsystem: CNet Technology Inc ProG-2000L
46: Kernel driver in use: r8169
47: Kernel modules: r8169

There is a workaround if I explicitly set the link speed to 100Mbps. (sudo ethtool -s eth0 speed 100 duplex full autoneg on wol d). Then the syslog is clear and everything is working as expected. Also on 3.2 and 3.5 kernels there is no such a problem.

Radoslav Petrov, given the Raring enablement kernel is EoL as per https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Kernel.2BAC8-Support.A12.04.x_Ubuntu_Kernel_Support , have you had a chance to test a later kernel version?
