I am looking at syzbot reports triggering kernel stack overflows
involving a cascade of ipvlan devices.
We can save 8 bytes in struct flowi_common.
This patch alone will not fix the issue, but is a start.
Fixes: 24ba14406c ("route: Add multipath_hash in flowi_common to make user-define hash")

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.
