The SoC mentioned in the link you provided is the APQ8084 that is 
introduced in the link below:
https://www.qualcomm.com/products/mobile/snapdragon/smartphones/snapdragon-8-series-mobile-platforms/snapdragon-processors-805

https://hwbot.org/hardware/processor/snapdragon_805_apq8084_pro__(8084_fusion_4.5)_2700mhz/

The driver here is for qca8084, which has the different prefix,
and qca8084 is the Ethernet CHIP like qca8081, but qca8084 is
multiple ports(quad-phy).
