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

181 * a single VRF. If VRF's are supported then
182 * the transport must be VRF aware. This means
183 * that every socket call coming in must be directed
184 * within the endpoint to one of the VRF's it belongs
185 * to. The endpoint, before binding, may select
186 * the "default" VRF it is in by using a set socket
187 * option with SCTP_VRF_ID. This will also

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