144 * Blocking I/O is enabled on any TCP type socket by default. For the UDP
145 * model if this is turned on then the socket buffer is shared for send
146 * resources amongst all associations.  The default for the UDP model is that
147 * is SS_NBIO is set.  Which means all associations have a separate send
148 * limit BUT they will NOT ever BLOCK instead you will get an error back
149 * EAGAIN if you try to send too much. If you want the blocking semantics you
150 * set this option at the cost of sharing one socket send buffer size amongst
151 * all associations. Peeled off sockets turn this option off and block. But
152 * since both TCP and peeled off sockets have only one assoc per socket this
153 * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
154 * model OR peeled off UDP model, but we do allow you to do so. You just use
155 * the normal syscall to toggle SS_NBIO the way you want.
156 *
157 * Blocking I/O is controlled by the SS_NBIO flag on the socket state so_state
158 * field.

208 * a single VRF. If VRF's are supported then
209 * the transport must be VRF aware. This means
210 * that every socket call coming in must be directed
211 * within the endpoint to one of the VRF's it belongs
212 * to. The endpoint, before binding, may select
213 * the "default" VRF it is in by using a set socket
214 * option with SCTP_VRF_ID. This will also
