V18.06.7 ath10k driver

Dear all,

I want to add WIFI 5G for my Router with QCA9531 + QCA9887 chipset.
So, I pull the OpenWrt to my PC, checkout to tag v18.06.7

then executing following commands:

./scripts/feeds update -a

./scripts/feeds install -a

make menuconfig

then I selected "Qualcomm Atheros AP147-010 reference board) for Target Profile,

but i only find "kmod-ath9k" instead of "kmod-ath10k",

Which sub-menu i can find the "kmod-ath10k" ?
