|  | Datagram Congestion Control Protocol (RFC 4340) | 
|  |  | 
|  | From https://www.ietf.org/rfc/rfc4340.txt: | 
|  |  | 
|  | The Datagram Congestion Control Protocol (DCCP) is a transport | 
|  | protocol that implements bidirectional, unicast connections of | 
|  | congestion-controlled, unreliable datagrams. It should be suitable | 
|  | for use by applications such as streaming media, Internet telephony, | 
|  | and on-line games. | 
|  |  | 
|  | To compile this protocol support as a module, choose M here: the | 
|  | module will be called dccp. | 
|  |  | 
|  | If in doubt, say N. |

|  | Only use this if you're hacking DCCP. | 
|  |  | 
|  | When compiling DCCP as a module, this debugging output can be toggled | 
|  | by setting the parameter dccp_debug of the `dccp' module to 0 or 1. | 
|  |  | 
|  | Just say N. |
