128 * Blocking I/O is enabled on any TCP type socket by default. For the UDP
129 * model if this is turned on then the socket buffer is shared for send
130 * resources amongst all associations.  The default for the UDP model is that
131 * is SS_NBIO is set.  Which means all associations have a seperate send
132 * limit BUT they will NOT ever BLOCK instead you will get an error back
133 * EAGAIN if you try to send to much. If you want the blocking symantics you
134 * set this option at the cost of sharing one socket send buffer size amongst
135 * all associations. Peeled off sockets turn this option off and block. But
136 * since both TCP and peeled off sockets have only one assoc per socket this
137 * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
138 * model OR peeled off UDP model, but we do allow you to do so. You just use
139 * the normal syscall to toggle SS_NBIO the way you want.
140 *
141 * Blocking I/O is controled by the SS_NBIO flag on the socket state so_state

174 * a single VRF. If VRF's are supported then
175 * the transport must be VRF aware. This means
176 * that every socket call coming in must be directed
177 * within the endpoint to one of the VRF's it belongs
178 * to. The endpoint, before binding, may select
179 * the "default" VRF it is in by using a set socket
180 * option with SCTP_VRF_ID. This will also

190 * VRF. They cannot reside in two (or more) VRF's. Incoming
191 * packets, assuming the router is VRF aware, can always
192 * tell us what VRF they arrived on. A host not supporting
193 * any VRF's will find that the packets always arrived on the
