ng_hole -- netgraph discard node type
The hole node type silently discards all data and control messages it
receives. This type is used for testing and debugging.
A ng_hole node accepts any request to connect, regardless of the hook
name, as long as the name is unique.
This node type supports only the generic control messages. Other control
messages are silently discarded.
This node shuts down upon receipt of a NGM_SHUTDOWN control message, or
when all hooks have been disconnected.

The ng_hole node type was implemented in FreeBSD 4.0.
