This patch series adds support for ctrl port tx status over nl80211. With this series, a clean separation between mgmt+ctrl (over nl80211) and in-kernel data path is possible for the first time. For each send control port frame, a cookie is returned in extended ack data. Therefore, a custom ack handler argument for send_and_recv is introduced. Afterwards, this is used by tx control port to plug in a cookie handler for netlink acks. When the kernel returns a tx status notification, the same event, as with socket tx status support is triggered. In the future, it is possible to compare only cookies on send/tx report if desired so. v2: mostly incorporated feedback from Johannes Berg * reorder patches * split ext ack handler and ack handler usage Markus Theil (6): nl80211: add custom ack handler to send_and_recv nl80211: handle control port tx status events over nl80211 nl80211: use control port tx (status) in AP mode if possible nl80211: print tx cookie value for ctrl port tx nl80211: add ack handler for extack cookies nl80211: use ext ack handler for tx ctrl port src/drivers/driver.h | 4 +- src/drivers/driver_nl80211.c | 342 +++++++++++++++++++---------- src/drivers/driver_nl80211.h | 4 +- src/drivers/driver_nl80211_capa.c | 25 ++- src/drivers/driver_nl80211_event.c | 29 +++ src/drivers/driver_nl80211_scan.c | 24 +- 6 files changed, 288 insertions(+), 140 deletions(-) -- 2.27.0 _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
