Just to be sure that we are talking about the same thing: I am (or actually
hostapd is) using NL80211_IFTYPE_AP_VLAN here - not 802.1Q.
then it might be something different. i'm not sure at that point. but
consider that AP_VLAN is also used for WDS STA/WDS AP implementations.
so each wds station becomes a individual interface on ap side for
bridging. that might of course have a influence to broadcast/multicast
frames
in addition the 10.4 firmware series has a special wmi flag which is not
used by ath10k, but solved alot of problems for me (in my case with
reauthentication)
WMI_VDEV_DISABLE_4_ADDR_SRC_LRN
this might be unrelated to your issue. but this flag must be set anyway
for proper work. but it isnt by default in all 10.4 firmwares.
the only option for you is using the CT firmware by candelatech, which
does not suffer from this issue.
Thanks for the interesting hint - but there is a twist :)
I've initially tried ath10k-ct with the candelatech firmware.
5.4.93+2021-01-11-9fe1df7d-1 with 10.4b-ct-4019-fW-13-5ae337bb1 to be more
precise. And later also switched to the ath10k backport from 5.8.18(-1-5).
Sorry for forgetting to mention such details in the first mail.
And I've just noticed that I was always testing with the ath10k-ct firmware
(which is the default in OpenWrt but never with the official one from Kalle's
ath10k-firmware tree. So I've just switched to QCA4019 hw1.0 10.4-3.6-00140
from the official tree and the problem went away.
For Ben Greear's firmware, the only workaround which I found until now was to
set NL80211_ATTR_MULTICAST_TO_UNICAST_ENABLED to 1 to force mac80211 to send
multicast as unicast.
so if its a pure multicast/unicast issue it could be also a basic rate
issue for ct firmwares.
lets see what ben has to say here.
Kind regards,
Sven
