Hi Martin,

To dig up an old thread - I've recently experienced similar issues that the rx error count increases on 82599, so I dug into the sources and realized that the MAC fault counters were being added to the rx error count.

The following patch removes the MAC local and remote fault counts from rx errors, and this has fixed the issue here:
http://dpdk.org/dev/patchwork/patch/8525/

If this issue is still open perhaps try the patch and see if it improves the situation.

On a related note, I'm currently implementing extended statistics for ixgbe, which showed me that the MAC faults were the root cause of the rx increase in my case.

-Harry
