Add the lines in bold to disable all IPv6 addresses on the VIF interfaces

# configure interfaces which act as pure bridge ports:
_setup_bridge_port() {
    local dev="$1"
    local virtual="$2"

    # take interface down ...
    ip link set ${dev} down

    if [ $virtual -ne 0 ] ; then
        # Initialise a dummy MAC address. We choose the numerically
        # largest non-broadcast address to prevent the address getting
        # stolen by an Ethernet bridge for STP purposes.
        # (FE:FF:FF:FF:FF:FF)
        ip link set ${dev} address fe:ff:ff:ff:ff:ff || true
    fi

    # ... and configure it
