Subject: atl1c: networking bug - increasing counters with no data.

Hi all, 

I have a atl1c networking card in my laptop - it's not connected since i
use wifi instead.

After a while of uptime it seems like it goes haywire, tools are
currently reporting data transfers of ~9GB/s

ifconfig eth0
eth0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

The only changes i have been able to spot was the __dev* cleanups... 

git log HEAD...v3.7.3 --format=oneline -- drivers/net/ethernet/atheros/atl1c/
1dd06ae8db716e17ec7e06244b858606edf378c0 drivers/net: fix up function prototypes after __dev* removals
093d369d4e8e8b6361317edd83935bdf8a0c83de net/atheros: remove __dev* attributes

And I'm currently running: v3.8-rc4-139-g1d85490

(It takes a while to recreate... )
