commit7c9f131f36upstream. net/mlx5: Expose MPFS configuration API MPFS is the multi physical function switch that bridges traffic between the physical port and any physical functions associated with it. The driver is required to add or remove MAC entries to properly forward incoming traffic to the correct physical function. We export the API to control MPFS so that other drivers, such as mlx5_vdpa are able to add MAC addresses of their network interfaces. The MAC address of the vdpa interface must be configured into the MPFS L2 address. Failing to do so could cause, in some NIC configurations, failure to forward packets to the vdpa network device instance. Fix this by adding calls to update the MPFS table.

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.
