   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 *
  27 * GENL_struct(tag_name, tag_number, struct name, struct fields) - struct and policy
  28 *      genl_magic_struct.h
  29 *              generates the struct declaration,
  30 *              generates an entry in the tla enum,
  31 *      genl_magic_func.h
  32 *              generates an entry in the static tla policy
  33 *              with .type = NLA_NESTED
  34 *              generates the static <struct_name>_nl_policy definition,
  35 *              and static conversion functions
  36 *
  37 *      genl_magic_func.h
  38 *
  39 * GENL_mc_group(group)
  40 *      genl_magic_struct.h
  41 *              does nothing
  42 *      genl_magic_func.h
  43 *              defines and registers the mcast group,
  44 *              and provides a send helper
  45 *
  46 * GENL_notification(op_name, op_num, mcast_group, tla list)
  47 *      These are notifications to userspace.
  48 *
  49 *      genl_magic_struct.h
  50 *              generates an entry in the genl_ops enum,
  51 *      genl_magic_func.h
  52 *              does nothing
  53 *
  54 *      mcast group: the name of the mcast group this notification should be
  55 *      expected on
  56 *      tla list: the list of expected top level attributes,
  57 *      for documentation and sanity checking.
  58 *
  59 * GENL_op(op_name, op_num, flags and handler, tla list) - "genl operations"
  60 *      These are requests from userspace.
  61 *
  62 *      _op and _notification share the same "number space",
  63 *      op_nr will be assigned to "genlmsghdr->cmd"
  64 *
  65 *      genl_magic_struct.h
  66 *              generates an entry in the genl_ops enum,
  67 *      genl_magic_func.h
  68 *              generates an entry in the static genl_ops array,
  69 *              and static register/unregister functions to
  70 *              genl_register_family_with_ops().
  71 *
  72 *      flags and handler:
  73 *              GENL_op_init( .doit = x, .dumpit = y, .flags = something)
  74 *              GENL_doit(x) => .dumpit = NULL, .flags = GENL_ADMIN_PERM
  75 *      tla list: the list of expected top level attributes,
  76 *      for documentation and sanity checking.
