 * uIP TCP/IP stack signals.
 * \author Adam Dunkels <[e-mail]>
 *
 * The signals defined in this module usually is not used by
 * application programmers, but knowledge of these signals are useful
 * for developers of network device drivers.
 *
 * These signals can be used to force a poll of a specific uIP
 * connection. This usually is used after doing e.g. a TCP connect
 * that normally would not take place until next time the connection
 * was periodically polled (normally up to 0.5 seconds afterwards). By
 * emitting the signals defined by this module, the poll will take
 * place at once the signal is delivered.
