RE: Ethernet CRC errors statistics in Linux
It could be that the driver you are using doesn't report those statistics. It's also possible you haven't had any errors in that
time. In my statistics below, the send/receive byte counts have overflowed the 32-bit limit many times, so don't believe them. I
probably download 2-10 gigabytes per day, and the uptime is 33 days.
