    [DCCP]: Factor out common code for generating Resets · e356d37a
    Gerrit Renker authored
    This factors code common to dccp_v{4,6}_ctl_send_reset into a separate function,
    and adds support for filling in the Data 1 ... Data 3 fields from RFC 4340, 5.6.
    
    It is useful to have this separate, since the following Reset codes will always
    be generated from the control socket rather than via dccp_send_reset:
     * Code 3, "No Connection", cf. 8.3.1;
     * Code 4, "Packet Error" (identification for Data 1 added);
     * Code 5, "Option Error" (identification for Data 1..3 added, will be used later);
     * Code 6, "Mandatory Error" (same as Option Error);
     * Code 7, "Connection Refused" (what on Earth is the difference to "No Connection"?);
     * Code 8, "Bad Service Code";
     * Code 9, "Too Busy";
     * Code 10, "Bad Init Cookie" (not used).
    
    Code 0 is not recommended by the RFC, the following codes would be used in
    dccp_send_reset() instead, since they all relate to an established DCCP connection:
     * Code 1, "Closed";
     * Code 2, "Aborted";
     * Code 11, "Aggression Penalty" (12.3).
