George McCollister says: ==================== add HSR offloading support for DSA switches Add support for offloading HSR/PRP (IEC 62439-3) tag insertion, tag removal, forwarding and duplication on DSA switches. This series adds offloading to the xrs700x DSA driver. Changes since RFC: * Split hsr and dsa patches. (Florian Fainelli) Changes since v1: * Fixed some typos/wording. (Vladimir Oltean) * eliminate IFF_HSR and use is_hsr_master instead. (Vladimir Oltean) * Make hsr_handle_sup_frame handle skb_std as well (required when offloading) * Don't add hsr tag for HSR v0 supervisory frames. * Fixed tag insertion offloading for PRP. Changes since v2: * Return -EOPNOTSUPP instead of 0 in dsa_switch_hsr_join and dsa_switch_hsr_leave. (Vladimir Oltean) * Only allow ports 1 and 2 to be HSR/PRP redundant ports. (Tobias Waldekranz) * Set and remove HSR features for both redundant ports. (Vladimir Oltean) * Change port_hsr_leave() to return int instead of void. * Remove hsr_init_skb() proto argument.

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.
