18 randpktdump is a extcap tool that provides access to the random packet
19 generator (randpkt). It is mainly used for testing and educational
20 purpose.
21

40
41 --capture
42 Start capturing from specified interface save saved it in place
43 specified by --fifo.
44
45 --fifo=<path to file or pipe>
46 Save captured packet to file or send it through pipe.
47
48 --maxbytes=<bytes>
49 Set the max number of bytes per packet.
50
51 --count=<num>
52 Number of packets to generate (-1 for infinite).

62 true.
63
64 --type=<packet type>
65 Use the selected packet type. To list all the available packet
66 type, run randpktdump --help.
