The inner/outer modes were added to abstract out common code that were once duplicated between IPv4 and IPv6. As time went on the abstractions have been removed and we are now left with empty shells that only contain duplicate information. These can be removed one-by-one as the same information is already present elsewhere in the xfrm_state object. Just like the input-side, removing this from the output code makes it possible to use transport-mode SAs underneath an inter-family tunnel mode SA.

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.
