[ Upstream commit 23263ec86a5f44312d2899323872468752324107 ] When an ip6_tunnel is in mode 'any', where the transport layer protocol can be either 4 or 41, dst_cache must be disabled. This is because xfrm policies might apply to only one of the two protocols. Caching dst would cause xfrm policies for one protocol incorrectly used for the other.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
