    sctp: Fix SCTP_MAXSEG socket option to comply to spec. · f68b2e05
    Vlad Yasevich authored
    We had a bug that we never stored the user-defined value for
    MAXSEG when setting the value on an association.  Thus future
    PMTU events ended up re-writing the frag point and increasing
    it past user limit.  Additionally, when setting the option on
    the socket/endpoint, we effect all current associations, which
    is against spec.
    
    Now, we store the user 'maxseg' value along with the computed
    'frag_point'.  We inherit 'maxseg' from the socket at association
    creation and use it as an upper limit for 'frag_point' when its
    set.
