/*
* The following structure is the API Dispatch table. The structure is indexed
* by the _AFP code. Each entry consists of the routine address that handles
* the request and/or dispatches to FSP, the fixed size of the request
* packet and optionally three variable size packets. The fixed size request
* packet is further split up into SEVEN fields. Each field is of the type
* FLD_BYTE, FLD_WORD or FLD_DWRD. A field of the type FLD_WORD and FLD_DWRD
* is converted from on-the-wire format to the internal format. An FLD_NONE
* entry stops the scan for the fixed part of the request.
* NamexType where x is 1,2,3 defines what type of variable size packets
* follow. A NONE on any of the fields stops the parsing. A type of BLOCK
* consumes the balance of the packet. Each of the variable size packets are
* copied to the sda_Namex field which is defined as ANSI_STRING. For the
* TYP_BLOCK field, the Length field of the ANSI_STRING defines the length
* of the block. The motivation for this structure is to conserve memory.
* Since a request packet is 578 bytes long and most APIs use only a small
* subset of that, the fixed portion of the packet is copied to the SDA
* and a smaller buffer is allocated for the variable packet.
* The orignal buffer cannot be accessed once we return back from this call.
