Jiri Pirko says: ==================== mlxsw: Add support for partial multicast route offload Yotam says: Previous patchset introduced support for offloading multicast MFC routes to the Spectrum hardware. As described in that patchset, no partial offloading is supported, i.e if a route has one output interface which is not a valid offloadable device (e.g. pimreg device, dummy device, management NIC), the route is trapped to the CPU and the forwarding is done in slow-path. Add support for partial offloading of multicast routes, by letting the hardware to forward the packet to all the in-hardware devices, while the kernel ipmr module will continue forwarding to all other interfaces. Similarly to the bridge, the kernel ipmr module will forward a marked packet to an interface only if the interface has a different parent ID than the packet's ingress interfaces. The first patch introduces the offload_mr_fwd_mark skb field, which can be used by offloading drivers to indicate that a packet had already gone through multicast forwarding in hardware, similarly to the offload_fwd_mark field that indicates that a packet had already gone through L2 forwarding in hardware. Patches 2 and 3 change the ipmr module to not forward packets that had already been forwarded by the hardware, i.e. packets that are marked with offload_mr_fwd_mark and the ingress VIF shares the same parent ID with the egress VIF. Patches 4, 5, 6 and 7 add the support in the mlxsw Spectrum driver for trap and forward routes, while marking the trapped packets with the offload_mr_fwd_mark. ==================== Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
