2 * There are times when we hold open some UDP sockets, but can't do
3 * anything with incoming packets other than discard them. This
4 * situation holds for dummy one-sided endpoints, for gateway
5 * endpoints that haven't been fully connected yet, and for all RTCP
6 * packets at the moment.
7 *
8 * In this module we implement the generic UDP "black hole" sink.
