   From RFC 2131:
   The values to be passed in an 'option' tag may be too long to fit in
   the 255 octets available to a single option (e.g., a list of routers
   in a 'router' option [21]).  Options may appear only once, unless
   otherwise specified in the options document.  The client concatenates
   the values of multiple instances of the same option into a single
   parameter list for configuration.
