if CONFIG_NET_IPGRE is enabled, but CONFIG_IPV6 is disabled:
net/ipv4/ip_gre.c: In function ‘ipgre_err’:
net/ipv4/ip_gre.c:144:22: error: variable ‘data_len’ set but not used [-Werror=unused-but-set-variable]
144 | unsigned int data_len = 0;
| ^~~~~~~~
Fix this by moving all data_len processing inside the IPV6-only section
that uses its result.

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.
