Roi Dayan 5b33eba99f net/mlx5e: Properly get the PF number phys port name ndo 
Currently, we fail to retrieve the PF number in some cases (e.g
single ported cards, lag capability), this further results in a
call trace issued by the rtnetlink code, since the error value
is not -EOPNOTSUPP. Change the implementation to be independent
from the lag code and function properly on both two ports and
single ported cards.

Call Trace:

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.
