What is the difference between Qualcomm QCA9980 ( e.g. Linksys EA8500, Netgear R7500v2, TP-Link C2600) and QCA9984 (e.g. Netgear R7800, Zyxel NBG6817) WiFi chip sets in ath10k driver/firmware in OpenWrt?
When I look at specs for both these chip sets on Qualcomm website, both are Wave 2 and 4x4:4 MU-MIMO chip sets. The only difference I see in specs - QCA9884 has support for 160Mhz, but QCA9980 has max support for 80Mhz bandwidth.
But is this still a limitation in the open source ath10k or ath10k-ct drivers/firmware? If not, what else is the difference between these two chip sets? Thx.
