  10  * sequence of netlink attributes:
  11  * I chose to have all "top level" attributes NLA_NESTED,
  12  * corresponding to some real struct.
  13  * So we have a sequence of |tla, len|<nested nla sequence>
  14  *
  15  * nested nla sequence:
  16  * may be empty, or contain a sequence of netlink attributes
  17  * representing the struct fields.
  18  *
  19  * The tag number of any field (regardless of containing struct)
  20  * will be available as T_ ## field_name,
  21  * so you cannot have the same field name in two differnt structs.
  22  *
  23  * The tag numbers themselves are per struct, though,
  24  * so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
  25  * which we won't use here).
  26  * The tag numbers are used as index in the respective nla_policy array.
