Title:
  Recurring MAC address problem with ATL1E Driver after
  suspend/shutdown/restart/ethernet cable removal

Status in “udev” package in Ubuntu:
  New

Bug description:
  I've been having this bug for a while - i think since maverick meerkat
  and its 2.6.35 kernel?? (Ordinarily, 9/10 times i use my wireless
  connection, but i have to use wired at university and i've finally had
  enough of this issue :(

  (You can check any relevant hardware info you need from data in other
  bugs i've posted, but in short i'm on ubuntu 11.10 64bit on an Asus
  K51AE.)

  related lspci output:
  (02:00.0 Ethernet controller: Atheros Communications AR8121/AR8113/AR8114 Gigabit or Fast Ethernet (rev b0))

  So it's definitely the atl1e driver and everytime i
  shutdown/suspend/restart, the MAC address changes (this is a
  particular problem because the university MAC filters us, so i would
  have to reregister everytime, were it not for a few commands i picked
  up from helpful users to temporarily get around the problem:

  sudo ifconfig eth0 down
  sudo ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx
  sudo ifconfig eth0 up

  (Doing this changes the address to one i've registered previously
  ((However, this only lasts until i shutdown/restart/suspend/until i
  remove and reinsert the ethernet cable.))

  Sometimes, if i restart, it not only changes the MAC address but
  increments the name for the new connection, i.e. After a few restarts,
  i can end up being on connection eth8 - when this is the only wired
  connection i ever use.

  I've used dozens of kernels and many versions of ubuntu and lubuntu
  since this first happened (~Dec 2010 - Jan 2011) Possibly a regression
  somewhere?

  Steps to repeat:

  1) Start computer and log in. Check MAC address of wired connection and make a note of it.
  2) Unplug then reinsert the ethernet cable or Restart/Shutdown the computer.
  3) Check MAC address and see that it's different to before.
