Since UDP is a lossy protocol, the kernel does not guarantee that it will send
data its been handed, and will sometimes drop the packets if, for example, the
send or receive buffer are filled. It could also be that the packets got
corrupted on the wire, didn't checksum properly and were tossed out.
