+ * This file defines the structure, as seen from the outside, of any Management
+ * Information Base (MIB) implementation. It does not define the contents of the
+ * MIB.
+ *
+ * A MIB is implemented as a map of parameters, each identified by a unique Object ID.
+ * The contents of the map have to be filled in by the actual MIB implementation, by
+ * assigning to the GlobMibMap variable. The mib_param_t data type defines the format
+ * of each parameter in the map. *NOTE:* The length of the last entry in the map must
+ * be 0.
+ *
+ * One parameter must always be present in the MIB map: the system revision. It has
+ * to be set by assigning a value to the systemRevision variable.
+ *
+ * Parameters can be of any data type, and read / write or read only. To resemble
+ * the hierarchical structure of an SNMP MIB, each Object ID consists of four nibbles
+ * (uint16_t) where the more significant nibbles correspond to a higher level in the
+ * hierarchy.
+ *
+ * The contents of the map can be accessed with the fMibSetBytes() and fMibGetBytes()
+ * functions. The implementation of the MIB may also make its parameters accessible
+ * in a more "direct" way; that is left to the implementation. The fMibSetBytes() and
+ * fMibGetBytes() functions are made available to the user interface (see ui.h). In
+ * order to do so, fMibUiInit() must be called during device initialization.
+ *
+ * Additionally, for parameters that have an array as their value, the individual
+ * elements of the array can be accessed using the fMibIndexedSetBytes() and
+ * fMibIndexedGetBytes() functions. The functions are similar to their non-indexed
+ * variants (fMibSetBytes() and fMibGetBytes()), except that they expect the index of
+ * the element as an argument.
+ *
+ * fMibGetBytes() and fMibSetBytes() will normally copy bytes from the MIB parameter
+ * into a given place in memory, or from memory to the MIB parameter. This behaviour
+ * can be overruled by assigning a function to the setAction and / or getAction
+ * fields of the MIB parameter.
+ *
+ * For parameters that have an array as their value, the length field has a slightly
+ * different meaning: the most significant 16 bits contain the length of the array;
+ * the least significant 16 bits contain the width of the array (i.e. the size in
+ * bytes of the array's elements). This implies that the normal fMibGetBytes() and
+ * fMibSetBytes() cannot be used on these parameters; instead, a get and set action
+ * needs to be provided to interpret the length field in case of a non-indexed get
+ * or set.
+ *
+ * To access the MIB fields over the user interface, the module ID must be equal to
+ * MIB_MODULE_ID or 0x01. The data in the packet must have the following structure:
+ * <table>
+ *  <tr>
+ *   <th>Get (0x00) / Set (0x01) code</th>
+ *   <th>Object ID</th>
+ *   <th>Value (only for set)</th>
+ *  </tr>
+ *  <tr>
+ *   <td>1 Byte</td>
+ *   <td>2 Bytes</td>
+ *   <td>X bytes</td>
+ *  </tr>
+ * </table>
+ *
+ * <table>
+ *  <tr>
+ *   <th>Indexed Get (0x02) / Set (0x03) code</th>
+ *   <th>Object ID</th>
+ *   <th>Index</th>
+ *   <th>Value (only for set)</th>
+ *  </tr>
+ *  <tr>
+ *   <td>1 Byte</td>
+ *   <td>2 Bytes</td>
+ *   <td>2 Bytes</td>
+ *   <td>X bytes</td>
+ *  </tr>
+ * </table>
+ *
+ * The reply to this request will have the same structure, with the value always
+ * being present (in case of a Set as well as a Get request).
+ *
+ * In case an error occurs during a Set or Get request, an error is returned by
+ * fMibGetBytes(), fMibSetBytes() or the UI. See the UI Module's documentation for
+ * the format of an error reply. The applicable error codes are:
+ * <table>
+ *  <tr><th>0x01</th><td>Trying to set a read-only parameter.</td></tr>
+ *  <tr><th>0x02</th><td>Requested value out of range.</td></tr>
+ *  <tr><th>0x03</th><td>Object ID is unknown.</td></tr>
+ *  <tr><th>0x04</th><td>Provided index is incorrect.</td></tr>
+ * </table>
