                     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>

                     35: <p>The hook should be connectable directly to a link hook of the
