Fwd: CT firmware and linux kernel patches for OpenWRT( ar71xx - Tp-Link 1750AC )

[s prasad]

Hi Sven,

Thank you for your patch.

I applied that patch and tried to test by executing sending deauth
command using aireplay-ng. However, I got following error.

Please let me know if I need to do any.

I need to send De-authentication command in monitor mode.


Thanks and Regards,

Attached is the patch with the changes for mac80211. You still have to
select the "Firmware from Candelatech" under ath10k. Don't select
"Firmware optimized for AP operation (v10.1 / API v2)". I know that this
selection should be done more cleanly but I only needed it for testing :)

Also an example patch for the mentioned iw hack is attached.

You just have to checkout openwrt r46435 (in git
113f685179b34015d615530575c73e61fc913039), apply these two patches,
select your device, enable ath10k, enable the Candelatech firmware and
build it.

Kind regards,
        Sven
