132239310Sdim * is SS_NBIO is set.  Which means all associations have a seperate send

135239310Sdim * set this option at the cost of sharing one socket send buffer size amongst

137239310Sdim * since both TCP and peeled off sockets have only one assoc per socket this
138239310Sdim * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
