license: introduce SPDX identifiersThe DPDK uses the Open Source BSD-3-Clause license for the core librariesand drivers. The kernel components are naturally GPLv2 licensed.Many of the files in the DPDK source code contain the full text of theapplicable license. For example, most of the BSD-3-Clause files contain afull copy of the BSD-3-Clause license text.Including big blocks of License headers in all files blows up the sourcecode with mostly redundant information. An additional problem is that eventhe same licenses are referred to by a number of slightly varying textblocks (full, abbreviated, different indentation, line wrapping and/orwhite space, with obsolete address information, ...) which makes validationand automatic processing a nightmare.To make this easier, DPDK uses of a single line reference toUnique License Identifiers in source files as defined by the LinuxFoundation's SPDX project https://spdk.org.Adding license information in this fashion, rather than adding full licensetext, can be more efficient for developers; decreases errors; and improvesautomated detection of licenses. The current set of valid, predefined SPDXidentifiers is set forth on the SPDX License List athttps://spdx.org/licenses/.For example, to label a file as subject to the BSD-3-Clause license,the following text would be used as the top line of the file.SPDX-License-Identifier: BSD-3-ClauseNote: Any new file contributions in DPDK shall adhere to the above scheme.It is also recommended to replace or at least amend the existing licensetext in the code with SPDX-License-Identifiers.Any exception to DPDK IP policies shall be approved by DPDK tech board andDPDK Governing Board. Steps for any exception approval:1. Mention the appropriate license identifier form SPDX. If the license is not listed in SPDX Licenses. It is the submitters responsibiliity to get it first listed.2. Get the required approval from the DPDK Technical Board. Technical board may advise the author to check alternate means first. If no other alternatives are found and the merit of the contributions are important for DPDK's mission, it may decide on such exception with two-thirds vote of the members.3. Technical board then approach Governing board for such limited approval for the given contribution only.Any approvals shall be documented in "licenses/exceptions.txt" with recorddates.Note: From the legal point of view, this patch is supposed to be only achange to the textual representation of the license information, but in noway any change to the actual license terms. With this patch applied, allfiles will still be licensed under the same terms they were before.Signed-off-by: Hemant Agrawal Acked-by: Stephen Hemminger Acked-by: Thomas Monjalon List of files: /dpdk/README
