It looks like the frame gets artificially enlarged by something in between my call to send and the receiver, by 14 bytes (an ethernet header size). The bytes 'it' uses to pad are all the same, but always different. If I set the MTU to the correct size (that is, the ethernet *payload* size), then the packets simply don't get through (because they violate the MTU, in the eyes of 'it'). If I set the MTU larger, the packets fail my own checksum routine (because of the padding, and their size).
