Comment 19 for bug 1332420

Dear all,

thanks for fixing the issue. After installing the latest kernel (3.13.0-32.56) from -proposed, I have verified that the issue is now fixed.

As confirmed by the tcpdump:
root@ubuntu1404:~# tcpdump -n -i eth0 '(ip6)&&((udp port 546)||(udp port 547))'
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes
