Please try the test kernels here: http://people.redhat.com/linville/kernels/fc6/ Do these exhibit similar stats problems?

The counters seem to go wacky after resume from suspend-to-ram.
I've seen it, but can't confirm that it's a driver problem. I'll need more time on it.
check ethtool -S ethX - you'll see they're all 0xffffffff values, something is reading the stats before the pci device is back online.
I have a fix which will be sent to netdev shorty.
Created attachment 140306 [details] patch to fix garbled stats patch Which Auke sent to John and myself for backporting
closing this as its going upstream
