CPE710 V1.0 QCA9563 (ath79) or QCA9888 (ath10k)

After some guidance - looking at the CPE710 V1 OWRT it has the Atheros QCA9888 driver by Candela. But this device uses an Atheros QCA5 and it shows at this in OWRT Qualcomm Atheros QCA956X ver 1 rev 0

Why does the build have the 9888 driver and not the 9653 driver?
