The SET MAX LOCK command sets the device into SET_MAX_LOCK state.
After this command is completed, any other SET MAX commands except SET

the device returns command aborted.
The device remains in the SET MAX LOCK state until a power cycle or the
acceptance of SET MAX UNLOCK or SET MAX FREEZE LOCK command.
The READ NATIVE MAX ADDRESS command is not executed just before this
command. The command is the SET MAX ADDRESS command if it is the
