   3 * General overview:
   4 * full generic netlink message:
   5 * |nlmsghdr|genlmsghdr|<payload>
   6 *
   7 * payload:
   8 * |optional fixed size family header|<sequence of netlink attributes>
   9 *
  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.
  27 *
  28 * GENL_struct(tag_name, tag_number, struct name, struct fields) - struct and policy
  29 *      genl_magic_struct.h
  30 *              generates the struct declaration,
  31 *              generates an entry in the tla enum,
  32 *      genl_magic_func.h
  33 *              generates an entry in the static tla policy
  34 *              with .type = NLA_NESTED
  35 *              generates the static <struct_name>_nl_policy definition,
  36 *              and static conversion functions
  37 *
  38 *      genl_magic_func.h
  39 *
  40 * GENL_mc_group(group)
  41 *      genl_magic_struct.h
  42 *              does nothing
  43 *      genl_magic_func.h
  44 *              defines and registers the mcast group,
  45 *              and provides a send helper
  46 *
  47 * GENL_notification(op_name, op_num, mcast_group, tla list)
  48 *      These are notifications to userspace.
  49 *
  50 *      genl_magic_struct.h
  51 *              generates an entry in the genl_ops enum,
  52 *      genl_magic_func.h
  53 *              does nothing
  54 *
  55 *      mcast group: the name of the mcast group this notification should be
  56 *      expected on
  57 *      tla list: the list of expected top level attributes,
  58 *      for documentation and sanity checking.
  59 *
  60 * GENL_op(op_name, op_num, flags and handler, tla list) - "genl operations"
  61 *      These are requests from userspace.
  62 *
  63 *      _op and _notification share the same "number space",
  64 *      op_nr will be assigned to "genlmsghdr->cmd"
  65 *
  66 *      genl_magic_struct.h
  67 *              generates an entry in the genl_ops enum,
  68 *      genl_magic_func.h
  69 *              generates an entry in the static genl_ops array,
  70 *              and static register/unregister functions to
  71 *              genl_register_family().
