A command line tool to send arbitrary IP packets. It has a large number
of command line options to specify the content of every header of a BGP,
RIP, TCP, UDP, ICMP, or raw IPv4 or IPv6 packet.  It also allows any data
to be added to the packet. Checksums can be calculated automatically,
but if you wish to send out wrong checksums, that is supported too.
