gluon/patches/openwrt/0073-ar71xx-add-kernel-support-for-the-OpenMesh-OM5P-ACv2.patch
Sven Eckelmann 69ce123457 ar71xx-generic: Add support for OpenMesh MR1750/OM5P-AC 
The new ath9k/ath10k based devices are only available in OpenWrt trunk. The
relevant patches have to backported to add support for them in Gluon
