I see that the MTU of my ethernet interface is 1500 bytes. Yet when I capture traffic, it's showing up as 1514 bytes.  I can account for 1500 bytes (1460 bytes of application data, plus ip header and tcp header).  Where are the 14 bytes showing up from?
Thanks

According to this:

The MAC header is 14 bytes - could that be what you are seeing?
