    sctp: add SCTP_PR_SUPPORTED on sctp sockopt · 28aa4c26
    Xin Long 提交于
    According to section 4.5 of rfc7496, prsctp_enable should be per asoc.
    We will add prsctp_enable to both asoc and ep, and replace the places
    where it used net.sctp->prsctp_enable with asoc->prsctp_enable.
    
    ep->prsctp_enable will be initialized with net.sctp->prsctp_enable, and
    asoc->prsctp_enable will be initialized with ep->prsctp_enable. We can
    also modify it's value through sockopt SCTP_PR_SUPPORTED.
