   18: <p>This chapter describes commands that are specific to netgraph type links.
   19: These commands apply to the currently active link, and are only
   20: valid if the currently active link has type <b>ng</b>.</p>
   21: <p>Note that this device type has no direct way to detect a physical layer
   22: disconnection (i.e., what would be analogous to loss of carrier detect)
   23: except by receiving a write error. One way to achieve this is to
   24: insure that when the physical layer goes down, the connection to
   25: the Netgraph hook is broken.</p>

   29: <dt><b><code>set ng node <em>nodepath</em></code></b><dd>
   30: <dt><b><code>set ng hook <em>hook</em></code></b><dd><p>These commands configure which Netgraph node, and which hook on that
   31: node, mpd is supposed to connect to. The node is found via the
   32: absolute Netgraph address <code><em>nodepath</em></code> and must have
   33: a free hook named <code><em>hook</em></code>. Both of these commands
   34: are required.</p>
   35: <p>The hook should be connectable directly to a link hook of the
   36: <code>ng_ppp(3)</code> netgraph node type.  That is, it should be
   37: prepared to transmit and receive PPP frames starting with the
   38: address and control fields (unless compressed), followed by the
   39: PPP protocol number and information fields, but containing no
   40: checksum field.</p>
