[ Upstream commit45a98ef492] The inner_ipproto saves the inner IP protocol of the plain text packet. This allows vendor's IPsec feature making offload decision at skb's features_check and configuring hardware at ndo_start_xmit, current code implenetation did not handle the case where IPsec is used in tunnel mode. Fix by handling the case when IPsec is used in tunnel mode by reading the protocol of the plain text packet IP protocol.

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.
