[ Upstream commitee614c8710] Function nfp_flower_repr_get_type_and_port expects an enum nfp_repr_type return value but, if the repr type is unknown, returns a value of type enum nfp_flower_cmsg_port_type. This means that if FW encodes the port ID in a way the driver does not understand instead of dropping the frame driver may attribute it to a physical port (uplink) provided the port number is less than physical port count. Fix this and ensure a net_device of NULL is returned if the repr can not be determined.

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.
