FEC Errors?

    I've heard FEC errors aren't as bad as CRC errors but I'm still concerned that I'm getting this many.

    This is after five minutes uptime. Checking the stats every now and then I've noticed that FECs go up about 100 a minute while CRCs don't seem to increase much at all.

    What are these?

    EDIT: I just realised I'd left some torrents uploading while testing this. Could that figure into it at all?
