Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating. Jira: ZEP-1457 Change-Id: I6131a1d4ee0e58f5b938300c2d2fc77d2e69572c Signed-off-by: David B.

zperf: Network Traffic Generator ################################ Description =========== zperf is a network traffic generator for Zephyr that may be used to evaluate network bandwidth. Features ========= - Compatible with iPerf_2.0.5. - Client or server mode allowed without need to modify the source code. - Working with task profiler (PROFILER=1 to be set when building zperf) Supported Boards ================ zperf is board-agnostic. However, to run the zperf sample application, the target platform must provide a network interface supported by Zephyr. This sample application has been tested on the following platforms: - Freedom Board (FRDM K64F) - Quark SE C1000 Development Board - QEMU x86 Requirements ============ - iPerf 2.0.5 installed on the host machine - Supported board Depending on the network technology chosen, extra steps may be required to setup the network environment. Usage ===== If Zephyr acts as a client, iPerf must be executed in server mode. For example, the following command line must be used for UDP testing: .. code-block:: console $ iperf -s -l 1K -u -V -B 2001:db8::2 In the Zephyr console, zperf can be executed as follows: .. code-block:: console zperf> udp.upload 2001:db8::2 5001 10 1K 1M If the IP addresses of Zephyr and the host machine are specified in the config file, zperf can be started as follows: .. code-block:: console zperf> udp.upload2 v6 10 1K 1M If Zephyr is acting as a server, set the download mode as follows: .. code-block:: console zperf> udp.download 5001 and in the host side, iPerf must be executed with the following command line: .. code-block:: console $ iperf -l 1K -u -V -c 2001:db8::1 -p 5001 iPerf output can be limited by using the -b option if Zephyr is not able to receive all the packets in orderly manner.
