  * 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.

  * any VRF's will find that the packets always arrived on the
