The main advantage of using attributes - * over packing everything into the family header is that the interface - * stays extendable as new attributes can supersede old attributes while - * remaining backwards compatible. Also attributes can be defined optional - * thus avoiding the transmission of unnecessary empty data blocks. - * Special nested attributes allow for more complex data structures to - * be transmitted, e.g. trees, lists, etc. - * - * While not required, netlink attributes typically follow the family - * header of a netlink message and must be properly aligned to NLA_ALIGNTO: - * @code - * +----------------+- - -+---------------+- - -+------------+- - -+ - * | Netlink Header | Pad | Family Header | Pad | Attributes | Pad | - * +----------------+- - -+---------------+- - -+------------+- - -+ - * @endcode - * - * The actual attributes are chained together each separately aligned to - * NLA_ALIGNTO.

This data type information is - * not encoded in the attribute, both the kernel and userspace part - * are required to share this information on their own. - * - * One of the major advantages of these basic types is the automatic - * validation of each attribute based on an attribute policy.

It is used for - * binary data of arbitary length. Typically this attribute carries - * a binary structure or a stream of bytes. - * @par - * @code - * // In this example, we will assume a binary structure requires to - * // be transmitted.
