/**
 * Server Layer Infor. ERO sub-object. 
 *  from  http://tools.ietf.org/html/draft-ietf-pce-inter-layer-ext-05. 
 * 
 *  This sub-object can be used for specifying the detail
   server layer information of a server layer path, e.g. the switching
   capability and encoding of the server layer path.

   The type of SERVER_LAYER_INFO sub-object is to be assigned by IANA.

   L: The L bit SHOULD NOT be set, so that the subobject represents a
   strict hop in the explicit route.

   Switching Capability (8 bits): see [RFC4203] for a description of
   parameters.
	From RFC 4230:
	The Switching Capability (Switching Cap) field contains one of the
   following values:
      1     Packet-Switch Capable-1 (PSC-1)
      2     Packet-Switch Capable-2 (PSC-2)
      3     Packet-Switch Capable-3 (PSC-3)
      4     Packet-Switch Capable-4 (PSC-4)
      51    Layer-2 Switch Capable  (L2SC)
      100   Time-Division-Multiplex Capable (TDM)
      150   Lambda-Switch Capable   (LSC)
      200   Fiber-Switch Capable    (FSC)
      



   Encoding (8 bits): see [RFC3471] for a description of parameters.
   

   Optional TLVs: Optional TLVs may be included within the object to
   specify more specific server layer path information (e.g., traffic
   parameters).

   This sub-object MAY be added immediately behind the node or link
   address sub-objects of the two edge nodes of a service path.
