Porting OpenBSD tcpbench into Linux (Just keep the basic features, and you need to install libevent before compiling tcpbench).

Check options:
$ ./tcpbench -h
Usage:
Client: tcpbench [-46Uuv] [-B buf] [-b addr] [-n connections]
[-p port] [-r interval] [-S space] [-t secs] hostname
Server: tcpbench -s [-46Uuv] [-B buf] [-p port] [-r interval]
[-S space] [hostname]
Options:
-4 Use IPv4 addresses.
-6 Use IPv6 addresses.
-B buf Specify the size of the internal read/write buffer used by
tcpbench. The default is 262144 bytes for TCP client/server and
UDP server. In UDP client mode this may be used to specify the
packet size on the test stream.
-b addr Specify the IP address of the interface which is used to send
the packets.
-n conns Use the given number of TCP connections (default: 1). UDP is
connectionless so this option isn't valid.
-p port Specify the port used for the test stream (default: 12345).
-r interval Specify the statistics interval reporting rate in milliseconds
(default: 1000).
-S space Set the size of the socket buffer used for the test stream. On
the client this option will resize the send buffer; on the server
it will resize the receive buffer.
-s Place tcpbench in server mode, where it will listen on all
interfaces for incoming connections. It defaults to using TCP if
-u is not specified.
-t secs Stop after secs seconds.
-U Use AF_UNIX sockets instead of IPv4 or IPv6 sockets. In client
and server mode hostname is used as the path to the AF_UNIX socket.
-u Use UDP instead of TCP; this must be specified on both the client
and the server. Transmitted packets per second (TX PPS) will be
accounted on the client side, while received packets per second
(RX PPS) will be accounted on the server side.
-v Display verbose output. If specified more than once, increase
the detail of information displayed.
