Linux kernel source tree

Devices that implement IPsec packet offload mode should offload SA and policies too. In RX path, it causes to the situation that HW will always have higher priority over any SW policies. It means that we don't need to perform any search of inexact policies and/or priority checks if HW policy was discovered. In such situation, the HW will catch the packets anyway and HW can still implement inexact lookups. In case specific policy is not found, we will continue with packet lookup and check for existence of HW policies in inexact list. HW policies are added to the head of SPD to ensure fast lookup, as XFRM iterates over all policies in the loop. The same solution of adding HW SAs at the begging of the list is applied to SA database too. However, we don't need to change lookups as they are sorted by insertion order and not priority.

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.
