 * 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

 *  and provides a send helper
 *
 * GENL_notification(op_name, op_num, mcast_group, tla list)
 * These are notifications to userspace.
 *

 * tla list: the list of expected top level attributes,

 *
 * 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,
