Packets that match the output xfrm policy are delivered to the netstack.
In IPsec packet mode for tunnel mode, the HW is responsible for building
the hard header and outer IP header. In such a situation, the inner
header may refer to a network that is not directly reachable by the host,
resulting in a failed neighbor resolution. The packet is then dropped.
xfrm policy defines the netdevice to use for xmit so we can send packets
directly to it.
Makes direct xmit exclusive to tunnel mode, since some rules may apply
in transport mode.
Fixes: f8a70afafc ("xfrm: add TX datapath support for IPsec packet offload mode")

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.
