Store rtm->rtm_tos in a dscp_t variable, which can then be used for setting fl4.flowi4_tos and also be passed as parameter of ip_route_input_rcu(). The .flowi4_tos field is going to be converted to dscp_t to ensure ECN bits aren't erroneously taken into account during route lookups. Having a dscp_t variable available will simplify that conversion, as we'll just have to drop the inet_dscp_to_dsfield() call. Note that we can't just convert rtm->rtm_tos to dscp_t because this structure is exported to user space.

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.
