This is the .config file of the build from your used custom image.
I assume you have setup build environment as here
The procedure to build this custom image by yourself is:
git clone https://github.com/openwrt/openwrt.gitgit clone https://github.com/infinitnet/lede-ar71xx-optimized-archer-c7-v2.gitcd openwrt./scripts/feeds update -a && ./scripts/feeds install -apatch -p1 < $(find ../lede-ar71xx-optimized-archer-c7-v2/patches -name "*.patch" | sort)cp -r ../lede-ar71xx-optimized-archer-c7-v2/files .cp ../lede-ar71xx-optimized-archer-c7-v2/config.seed ./.configmake defconfig-
make menuconfig# optional: enable debugfs and probably other stuff make download world -j4
If you are afraid of building your image yourself... You could try my ath79 C7v2 build...
Don“t think your used "optimized" image is much faster than the ath79 build!
Here you will have flow offload and debugfs... No need for this shortcut fe enabled build and you could install all packages you want with opkg.
