/*
 * There are times when we hold open some UDP sockets, but can't do
 * anything with incoming packets other than discard them.  This
 * situation holds for dummy one-sided endpoints, for gateway
 * endpoints that haven't been fully connected yet, and for all RTCP
 * packets at the moment.
 *
 * In this module we implement the generic UDP "black hole" sink.
