/*
 * NetLabel - A management interface for maintaining network packet label
 *            mapping tables for explicit packet labling protocols.
 *
 * Network protocols such as CIPSO and RIPSO require a label translation layer
 * to convert the label on the packet into something meaningful on the host
 * machine.  In the current Linux implementation these mapping tables live
 * inside the kernel; NetLabel provides a mechanism for user space applications
 * to manage these mapping tables.
 *
 * NetLabel makes use of the Generic NETLINK mechanism as a transport layer to
 * send messages between kernel and user space.  The general format of a
 * NetLabel message is shown below:
 *
 *  +-----------------+-------------------+--------- --- -- -
 *  | struct nlmsghdr | struct genlmsghdr | payload
 *  +-----------------+-------------------+--------- --- -- -
 *
 * The 'nlmsghdr' and 'genlmsghdr' structs should be dealt with like normal.
 * The payload is dependent on the subsystem specified in the
 * 'nlmsghdr->nlmsg_type' and should be defined below, supporting functions
 * should be defined in the corresponding net/netlabel/netlabel_<subsys>.h|c
 * file.  All of the fields in the NetLabel payload are NETLINK attributes, see
 * the include/net/netlink.h file for more information on NETLINK attributes.
 *
