 * Classification of Name Server Objects
 *
 * +-----------------------------------+---------------------------+
 * |  Device (node) Specific           |  Port Specific            |
 * +-----------------------------------+---------------------------+
 * |  Node Name (NN)                   | Port type (PT)            |
 * |  Symbolic Node Name Length        | Port Id (ID)              |
 * |  Symbloic Node Name(SNN)          | Symbolic Port Name length |
 * |  Initial Process associator(IPA)  | Symbolic Port Name (SPN)  |
 * |                                   | Class of Service (CS)     |
 * |                                   | fc4 types (FT)            |
 * |                                   | IP Address (IP)           |
 * +-----------------------------------+---------------------------+
 *
 * The above classification causes some inconvenience in not having
 * the ability to directly copy all the nameserver objects into a
 * contiguous piece of memory. But we'll live with it.
