Re: [IPsec] Draft-zhang-ipsecme-anti-replay: IPsec anti-replay algorithm without bit-shifting

In section 3 please add the appropriate license for code components 
(http://trustee.ietf.org/license-info/IETF-Trust-License-Policy-20091228.pdf). 
  In a nutshell encapsulate the code with:

<CODE BEGINS>
	code goes here
<CODE ENDS>

and right after <CODE BEGINS> include the following:

/*

    */

In section 6 you need to say whether the references are normative or 
not.  I assume normative.
