#6405 closed defect (wontfix)

madwifi - 802.11h channel switch announcement is broken

Description

Sending channel switch announcement from AP using iwpriv ath0 doth_chanswitch 36 20 is not working correctly.

doth is enabled in wireless configuration:

# iwpriv ath0 get_doth
ath0      get_doth:1

Eventually, channel is changed, but it seems that STAs do not receive announcement as channel change is not completed seamlessly but with traffic disruption.

Old madwifis, like 0.9.4, trunk from madwifi-project.org etc, work without disruption in traffic - STA just switches to the new channel. I think that problem lies within AP as it appeared when I switched old madwifi-0.9.4 AP to openwrt madwifi, keeping old madwifi on the STA.

Correctly sending CSA is important to me as it is used on many of my p-t-p links with lot of traffic; changing channel with STA scanning channels brings up other problems with madwifi, e.g. introduces some kinf of "processing overhead" which rises RTT from 1-2ms to 200-300ms.
