/*
 * General overview:
 * full generic netlink message:
 * |nlmsghdr|genlmsghdr|<payload>
 *
 * payload:
 * |optional fixed size family header|<sequence of netlink attributes>
 *
 * sequence of netlink attributes:
 * I chose to have all "top level" attributes NLA_NESTED,
 * corresponding to some real struct.
 * So we have a sequence of |tla, len|<nested nla sequence>
 *
 * nested nla sequence:
 * may be empty, or contain a sequence of netlink attributes
 * representing the struct fields.
 *
 * The tag number of any field (regardless of containing struct)
 * will be available as T_ ## field_name,
 * so you cannot have the same field name in two differnt structs.
 *
 * The tag numbers themselves are per struct, though,
 * so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
 * which we won't use here).
 * The tag numbers are used as index in the respective nla_policy array.
 *
 * GENL_struct(tag_name, tag_number, struct name, struct fields) - struct and policy
 *      genl_magic_struct.h
 *              generates the struct declaration,
 *              generates an entry in the tla enum,
 *      genl_magic_func.h
 *              generates an entry in the static tla policy
 *              with .type = NLA_NESTED
 *              generates the static <struct_name>_nl_policy definition,
 *              and static conversion functions
 *
 *      genl_magic_func.h
 *
 * GENL_mc_group(group)
 *      genl_magic_struct.h
 *              does nothing
 *      genl_magic_func.h
 *              defines and registers the mcast group,
 *              and provides a send helper
 *
 * GENL_notification(op_name, op_num, mcast_group, tla list)
 *      These are notifications to userspace.
 *
 *      genl_magic_struct.h
 *              generates an entry in the genl_ops enum,
 *      genl_magic_func.h
 *              does nothing
 *
 *      mcast group: the name of the mcast group this notification should be
 *      expected on
 *      tla list: the list of expected top level attributes,
 *      for documentation and sanity checking.
 *
 * GENL_op(op_name, op_num, flags and handler, tla list) - "genl operations"
 *      These are requests from userspace.
 *
 *      _op and _notification share the same "number space",
 *      op_nr will be assigned to "genlmsghdr->cmd"
 *
 *      genl_magic_struct.h
 *              generates an entry in the genl_ops enum,
 *      genl_magic_func.h
 *              generates an entry in the static genl_ops array,
 *              and static register/unregister functions to
 *              genl_register_family().
 *
 *      flags and handler:
 *              GENL_op_init( .doit = x, .dumpit = y, .flags = something)
 *              GENL_doit(x) => .dumpit = NULL, .flags = GENL_ADMIN_PERM
 *      tla list: the list of expected top level attributes,
 *      for documentation and sanity checking.
