The NVE flood profile is used for determining of offset applied to KVD address for NVE flood. We currently do not set it, leaving it at the default value of 0. That is not an issue: all the traffic-type-to-offset mappings (as configured by SFFP) default to offset of 0. This is what we need anyway, as mlxsw only allocates a single KVD entry for NVE underlay. The field is only relevant on Spectrum-2 and above. So to be fully consistent, we should split the existing controlled ops to Spectrum-1 and Spectrum>1 variants, with only the latter setting the field. But that seems like a lot of overhead for a single field whose meaning is "everything is the default". So instead pretend that the NVE flood profile does not exist in the controlled flood mode, like we have so far, and only set it when flood mode is CFF. Setting this at all serves dual purpose. First, it is now clear which profile belongs to NVE, because in the CFF mode, we have multiple users. This should prevent bugs in flood profile management. Second, using specifically non-zero value means there will be no valid uses of the profile 0, which we can therefore use as a sentinel.

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.
