package/kernel/mac80211/patches/912-wlcore-wl18xx-allow-CCK-rates-for-AP-mode.patch

   1 12xx chips allow only OFDM rates in AP mode for BT-Coex purposes. This
   2 is no longer required in 18xx chips, starting with FW 8.6.0.0.8.
   3
   4 Update the min allowed FW version in 18xx to support this functionality.
