igmpproxy does not start anymore with a working config from 2.2.6.

The reason seems to be that igmpproxy does not the recognize the interface.
My WAN (bge0) interface is configured for VLAN 7 (PPPOE) and VLAN 8 (DHCP).
igmpproxy is configured to use bge0_vlan8 as upstream. bge0_vlan8 is not recognized, only bge0 (which shouldn't).

The main network is 10.0/16.
In the subnet 10.0.15/24 there might be some clients using VLC to request multicast from igmpproxy.
The dedicated network 192.168.11/24 is used for the set top boxes (IPTV).
The network 192.168.1/24 is used for accessing the modem.

The config was used to created the attached log by calling igmpproxy manually via
igmpproxy -d -vvvv /tmp/igmpproxy.conf

This part seems most relevant:

There must be at least 2 Vif's where one is upstream.

bge0_vlan8 does not appear.
