Did you clarify it Cavium's legal team?
The permissions states that you should not add it to another publication
without written permission. DPDK can be considered a publication.
Did you got written permission?
The link specifically states that only the "The textural material and pictures
are copyright by the author" and "You are free to use, copy, and distribute any
of the code on this web site, whether modified by you or not".
The textural material in this case mean any text/pictures taken from the
Hacker's Delight book.
The linux kernel also uses similar code as seen at
https://github.com/torvalds/linux/blob/master/lib/div64.c.
Let me know if any further clarification are needed.
Thanks. It is clear now.

Pavan.
If not please specify Cavium's legal team opinion or take permission from
author. I believe that it is easy to obtain permission for this code.
"You are free to use, copy, and distribute any of the code on this web site,
whether modified by you or not. You need not give attribution. This includes
the algorithms (some of which appear in Hacker's Delight), the Hacker's
Assistant, and any code submitted by readers. Submitters implicitly agree to
this.
*The textural material and pictures are copyright by the author, and the
usual copyright rules apply. E.g., you may store the material on your
computer and make hard or soft copies for your own use. However, you may not
incorporate this material into another publication without written
permission from the author (which the author may give by email).*
The author has taken care in the preparation of this material, but makes no
