    dccp: Lockless integration of CCID congestion-control plugins · ddebc973
    Gerrit Renker authored
    Based on Arnaldo's earlier patch, this patch integrates the standardised
    CCID congestion control plugins (CCID-2 and CCID-3) of DCCP with dccp.ko:
    
     * enables a faster connection path by eliminating the need to always go 
       through the CCID registration lock;
    
     * updates the implementation to use only a single array whose size equals
       the number of configured CCIDs instead of the maximum (256);
    
     * since the CCIDs are now fixed array elements, synchronization is no
       longer needed, simplifying use and implementation.
    
    CCID-2 is suggested as minimum for a basic DCCP implementation (RFC 4340, 10);
    CCID-3 is a standards-track CCID supported by RFC 4342 and RFC 5348.
