321 - +type+ is the attribute type that will be stored in +struct nlattr.nla_type+
324 - +data+ contains arbitrary attribute payload.
326 - +len+ contains length of the +data+ attribute in bytes. If +data+ is +NULL+,
329 - +sublist+ contains a nested attribute list which will be appended after
340 - +header+ is the netlink header structure of the message. +NULL+ in the header
343 - +err+ points to the payload of +NLMSG_ERROR+ messages. It is set to +NULL+
346 - +payload+ is a pointer to message data.
348 - +payload_size+ is the length of +payload+ data in bytes.

395 this function will call +tst_brk()+ (or return 0 during test cleanup phase).

397 return 0 and store the first non-zero error code in global variable
