Hello,
I have 2 ath10k devices set in Mesh Point mode. When I use iptables'
DSCP target to set the WMM AC for some traffic ports to VO, the rules
work fine but only for unicast packets. All broadcast on the target
UDP ports goes out as BE, and not VO.
With some ath10k debugging enabled, it seems that the htt is indeed
sending the tx descriptor with the correct tid (6) set.
Is this the intended behavior for some reason? If not, is there any
more debugging on the TX path that I can do?
I don't think that WMM makes sense for bcast frames since they go out on
a special TID that does not do aggregation or per peer QoS settings.
I get that, but we want to give some WMM priority to bcast as they tend to have
higher probability of loss under high network loads.
That special TID that you mentioned, is it set in the ath10k fw?
Because I traced the
htt and it is sending the intended tid in the txbuf flags, but bcast
still come 0 (BE) on air.
Or am I missing something in the driver?
Thanks again for help.
Maybe you can convert bcast to unicast in the driver/mac80211? There are no
retries
or proper rate-ctrl for bcast either, so I don't think you can get great
performance
for bcast.
Thanks,
Ben
