fib_devindex_hashfn() converts a 32bit ifindex value to a 8bit hash. It makes no sense doing this from fib_info_hashfn() and fib_find_info_nh(). It is better to keep as many bits as possible to let fib_info_hashfn_result() have better spread. Only fib_info_devhash_bucket() needs to make this operation, we can 'inline' trivial fib_devindex_hashfn() in it.

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 reStructuredText 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.
