The chip flood broadcast and unknown multicast frames. On receive set skb->offload_fwd_mark to prevent the SW from flooding to the same ports. One exception: Because the ALR is set up to forward STP BPDUs only to CPU, the SW bridge should flood STP BPDUs if local STP is not enabled. This is archived by not setting skb->offload_fwd_mark on STP BPDUs. Signed-off-by: Egil Hjelmeland <privat@egil-hjelmeland.no> Reviewed-by: Andrew Lunn <andrew@lunn.ch> 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.
