From wikipedia ( http://en.wikipedia.org/wiki/BSD_licenses#3-clause_license_.28.22New_BSD_License.22.29 ):
"... allows unlimited redistribution for any purpose as long as its copyright notices and the license's disclaimers of warranty are maintained. The license also contains a clause restricting use of the names of contributors for endorsement of a derived
work without specific permission."
I believe you can redistribute any form of this code or binaries as long as you include a "COPYRIGHT" file that includes the original license.
I hope this helps you.
If you will integrate Pcap.Net into your commercially developed software, I would like to know that (just curios).
