While debugging some issues with neighbor query action frames, I ran into an interesting set of issues. For reasons I do not yet understand, sometimes wpa_supplicant has bss->freq == 0 when associated, and so sending an action frame chooses to send a 'command' frame instead of an mlme frame, because it thinks we are doing off-channel tx. When this happens, I end up seeing the action frame sent out on TID 6 in the ath10k firmware. This fails to send for a variety of reasons. When supplicant evidently has the proper bss->freq, then action frames go through the mlme code path, and then I see frames hit the ath10k firmware on the mgt tid as expected. I can hack around this in several different places, but in hopes of doing this more correctly: What exactly is supposed to configure the TID for off-channel TX? Thanks, Ben
Well, this was my bug after all, down in the firmware. Based on previous debugging though, likely the supplicant offchan thing will still need to be fixed so that we can send action frames to our AP on radar channels. I'm 4 bugs deep though, so stepping back up to bug 3 now that the TID issue is resolved. Enjoy, Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com
