Description: Index of hwBufferTable. This integer is a uniq number to identify the buffer module. We recommand two Number Plans in this paper, Logical Number or Phisical Number. For the first case, hwBufferModuleIndex is a integer, range from 1 to the Maximum number, for example 1,2,3,4,5 ..., where 1 represents the first buffer module, 2 represents the second buffer module, etc. For the second case hwBufferModuleIndex represents physical card position (Shelf Number, Frame Number, Slot Number, SubSlotNumber) where the buffer module residing, for example, 0x01020304 represent the buffer module on the 4th subslot of the 3th slot of the 2nd frame of the 1st Shelf.
