/**
 * BGP4CapabilitiesOptionalParameter.
 * 
 * 
 * RFC 3392.
 * 
 *  This is an Optional Parameter that is used by a BGP speaker to convey
   to its BGP peer the list of capabilities supported by the speaker.

   The parameter contains one or more triples <Capability Code,
   Capability Length, Capability Value>, where each triple is encoded as
   shown below:
 *        +------------------------------+
       | Capability Code (1 octet)    |
       +------------------------------+
       | Capability Length (1 octet)  |
       +------------------------------+
       | Capability Value (variable)  |
       +------------------------------+
 * 
   The use and meaning of these fields are as follows:

      Capability Code:

         Capability Code is a one octet field that unambiguously
         identifies individual capabilities.

      Capability Length:

         Capability Length is a one octet field that contains the length
         of the Capability Value field in octets.

      Capability Value:

         Capability Value is a variable length field that is interpreted
         according to the value of the Capability Code field.
