- * Since we know that most likely this function is called with buf aligned
- * on 4-byte boundary and 20 bytes in length, we can execution rather quickly
- * versus calling generic version of do_csum, which has lots of overhead in
- * handling various alignments and sizes.  However, due to lack of constrains
- * put on the function input argument, cases with alignment not on 4-byte or
- * size not equal to 20 bytes will be handled by the generic do_csum function.
