* Change MIT license texts to SPDX-License-Identifier SPDX-License-Identifier is much easier to understand and grep than license text so use that instead. * Change GPL exception license texts to SPDX-License-Identifier SPDX-License-Identifier is much easier to understand and grep than license text so use that instead. * Change misc license texts to SPDX-License-Identifier There are some external code in repo which are not licenses as most of the stuff in this repo. We still want every file to have SPDX identifier to easily grep licenses. * Add currently used license files Even though Bacnet-Stack is using SPDX identifiers we still need to give those license files with source. For this reason add all license files to license/ folder. SPDX has also files which would make same thing but this is style which example Linux kernel is using and it is quite clear so I choose that one for now. I choosed not yet bring CC-PDDC as that is not right license for those files. --------- Co-authored-by: Kari Argillander <kari.argillander@fidelix.com>

/** @defgroup DataLink The BACnet Network (DataLink) Layer
|
|
* <b>6 THE NETWORK LAYER </b><br>
|
|
* The purpose of the BACnet network layer is to provide the means by which
|
|
* messages can be relayed from one BACnet network to another, regardless of
|
|
* the BACnet data link technology in use on that network. Whereas the data
|
|
* link layer provides the capability to address messages to a single device
|
|
* or broadcast them to all devices on the local network, the network layer
|
|
* allows messages to be directed to a single remote device, broadcast on a
|
|
* remote network, or broadcast globally to all devices on all networks.
|
|
* A BACnet Device is uniquely located by a network number and a MAC address.
|
|
*
|
|
* Each client or server application must define exactly one of these
|
|
* DataLink settings, which will control which parts of the code will be built:
|
|
* - BACDL_ETHERNET -- for Clause 7 ISO 8802-3 ("Ethernet") LAN
|
|
* - BACDL_ARCNET -- for Clause 8 ARCNET LAN
|
|
* - BACDL_MSTP -- for Clause 9 MASTER-SLAVE/TOKEN PASSING (MS/TP) LAN
|
|
* - BACDL_BIP -- for ANNEX J - BACnet/IP
|
|
* - BACDL_ALL -- Unspecified for the build, so the transport can be
|
|
* chosen at runtime from among these choices.
|
|
* - Clause 10 POINT-TO-POINT (PTP) and Clause 11 EIA/CEA-709.1 ("LonTalk") LAN
|
|
* are not currently supported by this project.
|
|
*//** @defgroup DLTemplates DataLink Template Functions
|
|
* @ingroup DataLink
|
|
* Most of the functions in this group are function templates which are assigned
|
|
* to a specific DataLink network layer implementation either at compile time or
|
|
* at runtime.
