UDP definitely does _detect_ packet corruption, but it simply drops the
packet if it arrives with an invalid checksum.  There are no retry
abilities, so corruption simply counts as packet loss.  UDP also doesn't
guarantee that packets will arrive at the destination in the same order
they were sent in; and it doesn't have a concept of a "connection", so
there are no connect/disconnect/reset packets.
