+  BufferSize - Size of the buffer in bytes pointed to by Buffer / Actual size of
+               the variable data buffer.
+  Buffer     - Pointer to the buffer for data to be read.

+Returns:

+  EFI_SUCCESS           - Data was successfully retrieved into the provided 
+                          buffer and the BufferSize was sufficient to handle the

+                          be updated with the size required to complete the request.
+                          Buffer will not be affected.
+  EFI_INVALID_PARAMETER - BufferSize is NULL. BufferSize and Buffer will not be
+                          affected.
+  EFI_INVALID_PARAMETER - Buffer is NULL. BufferSize and Buffer will not be
+                          affected.
+  EFI_DEVICE_ERROR      - The iSCSI initiator name could not be retrieved due to
+                          a hardware error.
