Unfortunately, Mr. Harris's involvement with WinPcap is primarily as

     1) a developer of libpcap, primarily on UN*X systems (and  
primarily BSD at that)

and

     2) a developer of a program that uses libpcap/WinPcap (Ethereal)

rather than as a core developer of WinPcap, so directly asking him  
questions about WinPcap, rather than asking winpcap-users at winpcap.org  
(a list that includes the developers of WinPcap), is probably not the  
right thing to do.

I'll let the WinPcap developers answer this.

Is that Mike Shiffman's libnet?  If so, I think it should support  
that, but you should check the documentation.
