2  * General overview:
3  * full generic netlink message:
4  * |nlmsghdr|genlmsghdr|<payload>
5  *
6  * payload:
7  * |optional fixed size family header|<sequence of netlink attributes>
8  *
9  * sequence of netlink attributes:
10  * I chose to have all "top level" attributes NLA_NESTED,
11  * corresponding to some real struct.
12  * So we have a sequence of |tla, len|<nested nla sequence>
13  *
14  * nested nla sequence:
15  * may be empty, or contain a sequence of netlink attributes
16  * representing the struct fields.
17  *
18  * The tag number of any field (regardless of containing struct)
19  * will be available as T_ ## field_name,
20  * so you cannot have the same field name in two differnt structs.
21  *
22  * The tag numbers themselves are per struct, though,
23  * so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
24  * which we won't use here).
25  * The tag numbers are used as index in the respective nla_policy array.
26  *
