This patch adds support for Connect-X IPsec crypto offload by implementing the IPsec acceleration layer needed routines, which delegates IPsec offloads to Connect-X routines. In Connect-X IPsec, a Security Association (SA) is added or deleted via allocating a HW context of an encryption/decryption key and a HW context of a matching SA (IPsec object). The Security Policy (SP) is added or deleted by creating matching Tx/Rx steering rules whith an action of encryption/decryption respectively, executed using the previously allocated SA HW context. When new xfrm state (SA) is added: - Use a separate crypto key HW context. - Create a separate IPsec context in HW to inlcude the SA properties: - aes-gcm salt. - ICV properties (ICV length, implicit IV). - on supported devices also update ESN. - associate the allocated crypto key with this IPsec context. Introduce a new compilation flag MLX5_IPSEC for it. Downstream patches will implement the Rx,Tx steering and will add the update esn.

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.
