Ugh.   well Yay and ugh.   IPv6, apparently, uses multicast, not broadcast.   Multcast should be propigated to all ports on a bridge, but it's not.   Sometimes tweaking sys entries fixes it.   Sometimes quickly tweaking sys entries (I had a for loop with no sleep that set all ports to receive multicasts) crashes the box.  ugh.  sorry. 


(note, uh, it was pointed out that I said 'IPv6 uses multicast, not unicast' which doesn't really make sense.  I mean that in the places where IPv4 would use broadcast (FF:FF:FF:FF:FF) ethernet frames to map IPs to mac addresses, IPv6 uses multicast (x3:xx:xx:xx:xx:xx, but specifically 33:xx:xx:xx:xx:xx for IPv6 neigh discovery)  which should be treated the same by a bridge but apparently isn't always.)
