+ * driver the complete double word is translated using le32_to_cpu. Similarly
+ * After the driver writes into bitfields, cpu_to_le32 is used to translate the
+ * double words into required format.
+ * In order to avoid touching bits in shared structure more than once, temporary
+ * descriptors are used. These are passed as srcDesc to following functions.
