randpktdump is a extcap tool that provides access to the random packet
generator (randpkt). It is mainly used for testing and educational purpose.
--help
--version
--extcap-interfaces
List available interfaces.
--extcap-interface=<interface>
Use specified interfaces.
--extcap-dlts
List DLTs of specified interface.
--extcap-config
List configuration options of specified interface.
--capture
Start capturing from specified interface save saved it in place specified by
--fifo.
--fifo=<path to file or pipe>
Save captured packet to file or send it through pipe.
--maxbytes=<bytes>
Set the max number of bytes per packet.
--count=<num>
Number of packets to generate (-1 for infinite).
--delay=<ms>
Wait a number of milliseconds after writing each packet.
--random-type
Choose a random packet type for all packets if set to true.
--all-random
Choose a different random packet type for each packet if set to true.
--type=<packet type>
Use the selected packet type. To list all the available packet type, run
randpktdump --help.

Note
To stop capturing CTRL+C/kill/terminate the application.
