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

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

227 * VRF. They cannot reside in two (or more) VRF's. Incoming
228 * packets, assuming the router is VRF aware, can always
229 * tell us what VRF they arrived on. A host not supporting
