Horatiu Vulturv says: ==================== bridge: mrp: Extend br_mrp_switchdev_* This patch series extends MRP switchdev to allow the SW to have a better understanding if the HW can implement the MRP functionality or it needs to help the HW to run it. There are 3 cases: - when HW can't implement at all the functionality. - when HW can implement a part of the functionality but needs the SW implement the rest. For example if it can't detect when it stops receiving MRP Test frames but it can copy the MRP frames to CPU to allow the SW to determine this. Another example is generating the MRP Test frames. If HW can't do that then the SW is used as backup. - when HW can implement completely the functionality. So, initially the SW tries to offload the entire functionality in HW, if that fails it tries offload parts of the functionality in HW and use the SW as helper and if also this fails then MRP can't run on this HW. Based on these new calls, implement the switchdev for Ocelot driver. This is an example where the HW can't run completely the functionality but it can help the SW to run it, by trapping all MRP frames to CPU. Also this patch series adds MRP support to DSA and implements the Felix driver which just reuse the Ocelot functions. This part was just compiled tested because I don't have any HW on which to do the actual tests. v4: - remove ifdef MRP from include/net/switchdev.h - move MRP implementation for Ocelot in a different file such that Felix driver can use it. - extend DSA with MRP support - implement MRP support for Felix. v3: - implement the switchdev calls needed by Ocelot driver. v2: - fix typos in comments and in commit messages - remove some of the comments - move repeated code in helper function - fix issue when deleting a node when sw_backup was true ==================== Signed-off-by: David S.

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.
