>Description:
if you try to start pim6sd, the daemon stops immediately with "setsockopt 
MRT6_ADD_MIF on mif 1: Invalid argument"

my /etc/pim6sd.conf

default_phyint_status disable;
phyint vlan39 enable;
phyint vlan68 enable;
phyint vlan307 enable;
phyint vlan927 enable;

if you run the pim6sd with debuging, the /var/log/pim6sd.log shows:
