====================
selftests: fcnal: Test SO_DONTROUTE socket option.
The objective is to cover kernel paths that use the RTO_ONLINK flag
in .flowi4_tos. This way we'll be able to safely remove this flag in
the future by properly setting .flowi4_scope instead. With these
selftests in place, we can make sure this won't introduce regressions.
For more context, the final objective is to convert .flowi4_tos to
dscp_t, to ensure that ECN bits don't influence route and fib-rule
lookups (see commit a410a0cf98 ("ipv6: Define dscp_t and stop taking
ECN bits into account in fib6-rules")).
These selftests only cover IPv4, as SO_DONTROUTE has no effect on IPv6
sockets.
v2:
- Use two different nettest options for setting SO_DONTROUTE either
on the server or on the client socket.
- Use the above feature to run a single 'nettest -B' instance per
test (instead of having two nettest processes for server and
client).

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.
