Leon Romanovsky b79656ed44 RDMA/ipoib: Allow user space differentiate between valid dev_port
Systemd triggers the following warning during IPoIB device load:

 mlx5_core 0000:00:0c.0 ib0: "systemd-udevd" wants to know my dev_id.
        Should it look at dev_port instead?
        See Documentation/ABI/testing/sysfs-class-net for more info.

This is caused due to user space attempt to differentiate old systems
without dev_port and new systems with dev_port. In case dev_port will be
zero, the systemd will try to read dev_id instead.

There is no need to print a warning in such case, because it is valid
situation and it is needed to ensure systemd compatibility with old
kernels.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
