It looks like the bridge code sets the mtu value on this metric to the mtu of the bridge device in br_add_if(). So seems to be not really fixed to 1500. Not sure why netfilter really needs to have this 1500 in the metric before the mtu is initialized from the bridge code.
We could make fake_mtu() look like dn_dst_mtu(). The mtu of the bridge device should be reflected in the metric once the bridge code initialized it. Also learned pmtu values would be taken into account then.
