Btw., if in OpenWRT/LEDE you set 'option multicast_to_unicast 0'
in /etc/config/network for the bridge (and not bridge port)
then netifd should refrain from setting the bridge hairpinning and
AP isolation on wireless devices, too, if I remember correctly.

Can you confirm that the issue disappears for you then?
