Now we got your point. We are sorry for the confusion - it seems we
understood that wrong.

In order to force delivery of TX status frames for research and debugging
purposes, implement the IFF_ECHO flag for ieee80211 devices. When this flag
is set for a specific interface, IEEE80211_TX_CTL_REQ_TX_STATUS is enabled
in all packets s
At Technical University of Munich we use MAC 802.11 TX status frames to
perform several measurements in MAC 802.11 setups.
With ath based drivers this was possible until commit d94a461d7a7df6
("ath9k: use ieee80211_tx_status_noskb where possible") as the driver
ignored the IEEE80211_TX_CTL_REQ_TX_
