Its now possible to build a kernel that has no support for the classic
xtables get/setsockopt interfaces and builtin tables.
In this case, we have CONFIG_IP6_NF_MANGLE=n and
CONFIG_IP_NF_ARPTABLES=n.
For optstript, the ipv6 code is so small that we can enable it if
netfilter ipv6 support exists. For mark, check if either classic
arptables or NFT_ARP_COMPAT is set.

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.
