Fix streams in vLB/vDNS VNF
- Fixed an issue that prevented vPacketGen to run more than 2 streams - Improved DNS query load balancing by rehashing port numbers in the streams Change-Id: Iec962301712df505569dc210770ecf1aaf6e5c5c Issue-ID: CERT-1 Signed-off-by: Marco Platania <platania@research.att.com>
