>Description:
Using WPA encryption breaks IPv6 multicast. Without any encryption the node receives e.g. IPv6 Router Advertisements correctly, but when starting up wpa_supplicant with WPA/WPA2 (i.e. installing encryption keys into ccmp and tkip modules), the received IPv6 Router Advertisements are complete nonsense when looking with tcpdump. Unicast IPv6 and IPv4 continue working. Maybe there's something wrong in the decryption for multicast IPv6?
