[sami <1275220@xxxxxxxxxxxxxxxxxx>]

This bug is fixed as of Ubuntu 14.10beta2 which is shipping kernel 3.16.0-17-generic.
A backport would be welcome.
As a B plan we'll wait until LTS enablement stack provide 3.16 kernel (scheduled feb 2015).

Title:
  [Asus N56VZ] Atheros ALX driver : no more interface statistics

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This bug is a regression between 3.8 and 3.11 kernel.
  Since the new 3.11 kernel, there is no more network statistics on ALX cards.

  This has already been discussed here : http://comments.gmane.org/gmane.linux.network/278595
  But it seems not to be fixed.

  My card is an Atheros AR8161

  Here is an output of ifconfig:
            RX packets:0 errors:0 dropped:0 overruns:0 frame:0
            TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
            collisions:0 txqueuelen:1000 
            RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

  gnome system monitor is also affected
