During initialization of the NFP driver, a file name for loading application firmware is composed using the NIC's AMDA information and port type (count and speed). E.g.: "nic_AMDA0145-1012_2x10.nffw". In practice there may be many variants for each NIC type, and many of the variants relate to assembly components which do not concern the driver and application firmware implementation. Yet the current scheme leads to a different application firmware file name for each variant, because they have different AMDA information. To reduce proliferation of content-duplicated application firmware images or symlinks, the NIC's management firmware will only expose differences between variants that need different application firmware via a newly introduced hwinfo, "nffw.partno". Use of the existing hwinfo, "assembly.partno", is maintained in order to support for NICs with management firmware that does not expose "nffw.partno".

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.
