this series adds support for IPsec offload to the NFP driver.
It covers three enhancements:
1. Patches 1/3:
- Extend the capability word and control word to to support
new features.
2. Patch 2/3:

interact with upper layer are not implemented in this patch.
3. Patch 3/3:
- IPsec control plane interface xfrm callbacks are implemented
in this patch.

* Unnecessary logging removed
* Hook function xdo_dev_state_free in struct xfrmdev_ops removed

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.
