Question about Ack transmission for unicast #86

Open bupt-zsp opened 4 years ago

bupt-zsp commented 4 years ago

Dear open80211s team:

I am working on developing open802.11 by atheros NIC, and I want to know which part in driver/.../ath9k or mac802.11 control the ack transmission for unicast and I'm not sure about it.

Looking forward to your reply. Thanks.

IEEE80211_TX_CTL_NO_ACK should be configured at mac80211 and ath9k driver should honour it.

You may see whether you can extend iw to support no ACK policy.

Thanks for your reply, I can disable ack policy by modified IEEE80211_TX_CTL_NO_ACK and recompile linux kernel, I want to figure out which part of code transmission Ack in unicast and I want to realize fine-grained Ack transmission control. Whether I can control it?

You can dig a bit on the driver side and look for the tx path to experiment.
