RT_CONN_FLAGS(sk) overloads flowi4_tos with the RTO_ONLINK bit when sk has the SOCK_LOCALROUTE flag set. This allows ip_route_output_key_hash() to eventually adjust flowi4_scope. Instead of relying on special handling of the RTO_ONLINK bit, we can just set the route scope correctly. This will eventually allow to avoid special interpretation of tos variables and to convert ->flowi4_tos to dscp_t.

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.
