ng_ether_echo —
netgraph ether_echo node type
#include
<netgraph/ng_ether_echo.h>
The
ether_echo node type reflects all data and
control messages back to the sender. It assumes (and does not check) that the
packet is an ethernet frame, and swaps the source and destination addresses
before echoing it. This node type is used for testing and debugging.
A
ether_echo 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. Any other control
messages are reflected back to the sender.
This node shuts down upon receipt of a
NGM_SHUTDOWN
control message, or when all
hooks have been disconnected.
