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

 * the transport must be VRF aware. This means
 * that every socket call coming in must be directed

 * the "default" VRF it is in by using a set socket
 * option with SCTP_VRF_ID. This will also

 * the SCTP_ADD_VRF_ID call or deleted with
 * SCTP_DEL_VRF_ID.

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