Jiri Pirko says: ==================== Add support for offloading packet-sampling Yotam says: The first patch introduces the psample module, a netlink channel dedicated to packet sampling implemented using generic netlink. This module provides a generic way for kernel modules to sample packets, while not being tied to any specific subsystem like NFLOG. The second patch adds the sample tc action, which uses psample to randomly sample packets that match a classifier. The user can configure the psample group number, the sampling rate and the packet's truncation (to save kernel-user traffic). The last two patches add the support for offloading the matchall-sample tc command in the mlxsw driver, for ingress qdiscs. An example for psample usage can be found in the libpsample project at: https://github.com/Mellanox/libpsample v1->v2: - Reword first patch's commit message - Fix typo in comment in second patch - Change order of tc_sample uapi enum to match convention - Rename act_sample action callback tcf_sample -> tcf_sample_act ==================== 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.
