Nick Richardson says: ==================== pktgen: Add IMIX mode Adds internet mix (IMIX) mode to pktgen. Internet mix is included in many user-space network perf testing tools. It allows for the user to specify a distribution of discrete packet sizes to be generated. This type of test is common among vendors when perf testing their devices. [RFC link: https://datatracker.ietf.org/doc/html/rfc2544#section-9.1] This allows users to get a more complete picture of how their device will perform in the real-world. This feature adds a command that allows users to specify an imix distribution in the following format: imix_weights size_1,weight_1 size_2,weight_2 ... size_n,weight_n The distribution of packets with size_i will be (weight_i / total_weights) where total_weights = weight_1 + weight_2 + ... + weight_n For example: imix_weights 40,7 576,4 1500,1 The pkt_size "40" will account for 7 / (7 + 4 + 1) = ~58% of the total packets sent. This patch was tested with the following: 1. imix_weights = 40,7 576,4 1500,1 2. imix_weights = 0,7 576,4 1500,1 - Packet size of 0 is resized to the minimum, 42 3. imix_weights = 40,7 576,4 1500,1 count = 0 - Zero count. - Runs until user stops pktgen. Invalid Configurations 1. clone_skb = 200 imix_weights = 40,7 576,4 1500,1 - Returns error code -524 (-ENOTSUPP) when setting imix_weights 2. len(imix_weights) > MAX_IMIX_ENTRIES - Returns -7 (-E2BIG) This patch is split into three parts, each provide different aspects of required functionality: 1. Parse internet mix input. 2. Add IMIX Distribution representation. 3. Process and output IMIX results. Changes in v2: * Remove __ prefix outside of uAPI. * Use seq_puts instead of seq_printf where necessary. * Reorder variable declaration. * Return -EINVAL instead of -ENOTSUPP when using IMIX with clone_skb > 0 ==================== 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.
