Here are a few patches to fix the issues the multicast-to-unicast
feature of the bridge has: IGMP/MLD report suppression could lead
to multicast packet loss. Also see ticket #17625 .
As previously discussed on this mailing list, AP-isolation together
with bridge-hairpinning is a way to make the multicast-to-unicast
feature usable even if listeners potentially suppressing reports
are present: That way the bridge will get all reports and will have
full control on where to forward them. For instance *not* to other
STAs (unless there is a multicast router).
Furthermore [PATCH netifd 2/3] introduces a netifd option to disable
the multicast-to-unicast feature.
[PATCH netifd 3/3] is not related to this issue but introduces a
handy option (which I would like to make use of for IGMP/MLD domain
The OpenWRT specific patches should be applied after the netifd
patches arrived in OpenWRT.
* Removed [PATCH openwrt 1/3]:
Now included in [PATCH netifd 1/3] through netifd-wireless.sh
* Separated introduction of multicast_to_unicast configuration option
in separate patch
* passing multicast_to_unicast to netifd scripts via json from netifd
instead of external uci command calls
* Moved multicast_to_unicast uci option to be a bridge instead of
bridge member option
