This is to match ipv4 behaviour, see __ip_sock_set_tos() implementation. Technically for ipv6 this might not be required because normally we do not allow tclass to influence routing, yet the cli tooling does support it: lpk11:~# ip -6 rule add pref 5 tos 45 lookup 5 lpk11:~# ip -6 rule 5: from all tos 0x45 lookup 5 and in general dscp/tclass based routing does make sense. We already have cases where dscp can affect vlan priority and/or transmit queue (especially on wifi). So let's just make things match. Easier to reason about and no harm.

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.
