Quick questions to further debug the issue here, 1. Is this issue seen every time you start sending data traffic? 2. Issue seen with older firmwares? (FYR, http://linuxwireless.org/en/users/Drivers/ath10k/firmware/ ) 3. Could you please share the dmesg from your device after enabling MAC and WMI logs in ath10k driver To enable debug logs please see http://linuxwireless.org/en/users/Drivers/ath10k/debug/ 4. Do you know what is the Number of Spatial Streams seen in mesh beacons and in mesh data packet? Thanks, Ashok

RE: [PATCH] cfg80211: add debugfs VHT80 allow map
Hi Johannes, I see your point here. I will upload one patch for printing this info from iw. I will also write another patch for removing HT40 one?

We expose this data to userspace, so you could change 'iw' to print it when dumping the list of channels in 'iw list' or similar. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
