[ Upstream commit d36f45e5b4 ]
Address/port initialization should work correctly regardless
of the order in which command line arguments are supplied,
E.g, cfg_port should be used to connect to the remote host
even if it is processed after -D, src/dst address initialization
should not require that [-4|-6] be specified before
the -S or -D args, receiver should be able to bind to *.<cfg_port>
Achieve this by making sure that the address/port structures
are initialized after all command line options are parsed.
Store cfg_port in host-byte order, and use htons()
to set up the sin_port/sin6_port before bind/connect,
so that the network system calls get the correct values
in network-byte order.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
