29  *   |     Family Header    | Pad |           Attributes           |
59  *   nlmsg_attrdata(nlh, hdrlen)	head of attributes data
60  *   nlmsg_attrlen(nlh, hdrlen)		length of attributes data
65  *   nlmsg_parse()			parse attributes of a message
69  *   nlmsg_for_each_attr()		loop over all attributes
75  *                          Attributes Interface
116  * Nested Attributes Construction:
151  *   nla_validate()			validate a stream of attributes
152  *   nla_validate_nested()		validate a stream of nested attributes
153  *   nla_find()				find attribute in stream of attributes
154  *   nla_find_nested()			find attribute in nested attributes
156  *   nla_parse_nested()			parse nested attributes
157  *   nla_for_each_attr()		loop over all attributes
158  *   nla_for_each_nested()		loop over the nested attributes
256  *                         NLA_NESTED has the nested attributes directly inside
257  *                         while an array has the nested attributes at another
344 		 * validation is enforced for all attributes. For existing ones
345 		 * it should be set at least when new attributes are added to
464  *	extra data at the end of the message, attributes being longer than
465  *	they should be, or unknown attributes being present.
467  * @NL_VALIDATE_MAXTYPE: Reject attributes > max type; Together with _TRAILING
469  * @NL_VALIDATE_UNSPEC: Reject attributes with NLA_UNSPEC in the policy.
583  * nlmsg_attrdata - head of attributes data
595  * nlmsg_attrlen - length of attributes data
635  * nla_parse - Parse a stream of attributes into a tb buffer
643  * Parses a stream of attributes and stores a pointer to each attribute in
644  * the tb array accessible via the attribute type. Attributes with a type
645  * exceeding maxtype will be rejected, policy must be specified, attributes
660  * nla_parse_deprecated - Parse a stream of attributes into a tb buffer
668  * Parses a stream of attributes and stores a pointer to each attribute in
669  * the tb array accessible via the attribute type. Attributes with a type
670  * exceeding maxtype will be ignored and attributes from the policy are not
671  * always strictly validated (only for new attributes).
685  * nla_parse_deprecated_strict - Parse a stream of attributes into a tb buffer
693  * Parses a stream of attributes and stores a pointer to each attribute in
694  * the tb array accessible via the attribute type. Attributes with a type
696  * policy is not completely strictly validated (only for new attributes).
