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

[s prasad]

Hi Sven,

Your patch worked with following changes in
compat-wireless-2015-06-22/drivers/net/wireless/ath/ath10k/mac.c
+3686:

case ATH10K_HW_TXRX_RAW:
                /* FIXME: Packet injection isn't implemented. It should be
                 * doable with firmware 10.2 on qca988x.
                 */
                //WARN_ON_ONCE(1);
                //ieee80211_free_txskb(hw, skb);
                //return;
                break;

Thanks you so much.

Regards,
S Prasad
