  26 # Attach the ip (inet) protocol output of the protocol mux to the ip (inet)
  27 # input of a netgraph "interface" node (ifconfig should show it as "ng0").
  28 #if interface ng0 needs to be created use a mkpeer command.. e.g.
  29 ngctl mkpeer ${CARD}:rawdata.dlci${DLCI} iface inet inet
  30
  31 # if ng0 already exists, use a CONNECT command instead of a mkpeer. e.g.
  32 # ngctl connect ${CARD}:rawdata.dlci${DLCI} ng0: inet inet
  33
  34 # Then use ifconfig on interface ng0 as usual
  35
  36 # A variant on this whole set might use the 'name' command to make it more
  37 # readable. but it doesn't work if you have multiple lines or dlcis
  38 # e.g.
  39 # ngctl mkpeer ${CARD}: frame_relay rawdata downstream
  40 # ngctl name ${CARD}:rawdata mux
  41 # ngctl mkpeer mux: lmi dlci0 auto0
  42 # ngctl name mux:dlci0 lmi
  43 # ngctl connect mux: lmi: dlci1023 auto1023
  44 # ngctl mkpeer mux: rfc1490 dlci${DLCI} downstream
  45 # ngctl mux:dlci${DLCI} protomux
  46 # ngctl mkpeer protomux: iface inet inet
