From: Sean Hefty <sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
Provide an option for the user to indicate the type of
addresses used as input. Support hostname, IPv4, IPv6,
and GIDs.

+\-f address_format
+Specifies the format of the server and bind address. Be default, the
+format is determined by getaddrinfo() as either being a hostname, an IPv4
+address, or an IPv6 address. This option may be used to indicate that
+a specific address format has been provided. Supported address_format

+\-P port_space
+Specifies the port space for the connection. Be default, the port space
+is the RDMA TCP port space. (Note that the RDMA port space may be separate

\-c connections
The number of connections to establish between the client and server.
