PATCH 10/14 : Initialisation framework for feature negotiation
[DCCP]: Initialisation framework for feature negotiation
This initialises feature negotiation from two tables, which are initialised from sysctls. Furthermore, specifics of the implementation (e.g. currently short seqnos and ECN are not supported) are advertised for robustness.
