Linux kernel source tree
2111bb970c
Added implementation of backward-compatible (BWC) steering API. Native HWS API is very different from SWS API: - SWS is synchronous (rule creation/deletion API call returns when the rule is created/deleted), while HWS is asynchronous (it requires polling for completion in order to know when the rule creation/deletion happened) - SWS manages its own memory (it allocates/frees all the needed memory for steering rules, while HWS requires the rules memory to be allocated/freed outside the API In order to make HWS fit the existing fs-core steering API paradigm, this patch adds implementation of backward-compatible (BWC) steering API that has the bahaviour similar to SWS: among others, it encompasses all the rules' memory management and completion polling, presenting the usual synchronous API for the upper layer. A user that wishes to utilize the full speed potential of HWS can call the HWS async API and have rule insertion/deletion batching, lower memory management overhead, and lower CPU utilization. Such approach will be taken by the future Connection Tracking. Note that BWC steering doesn't support yet rules that require more than one match STE - complex rules. This support will be added later on. Reviewed-by: Erez Shitrit <erezsh@nvidia.com> Signed-off-by: Yevgeny Kliteynik <kliteyn@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> |

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.
