=head1 DESCRIPTION
B<randpktdump> is a extcap tool that provides access to the random
packet generator (randpkt). It is mainly used for testing and
educational purpose.
=head1 OPTIONS
=over 4
=item --help
Print program arguments.
=item --version
Print program version.
=item --extcap-interfaces
List available interfaces.
=item --extcap-interface=E<lt>interfaceE<gt>
Use specified interfaces.
=item --extcap-dlts
List DLTs of specified interface.
=item --extcap-config
List configuration options of specified interface.
=item --capture
Start capturing from specified interface save saved it in place specified by --fifo.
=item --fifo=E<lt>path to file or pipeE<gt>
Save captured packet to file or send it through pipe.
=item --maxbytes=E<lt>bytesE<gt>
Set the max number of bytes per packet.
=item --random-type
Choose a random packet type for all packets if set to true.
=item --all-random
Choose a different random packet type for each packet if set to true.
=item --type=E<lt>packet typeE<gt>
Use the selected packet type. To list all the available packet type, run randpktdump --help.
