The driver first supports Filogic 680 PCI device, which is a Wi-Fi 7 chipset supporting concurrent tri-band operation at 6 GHz, 5 GHz, and 2.4 GHz with 4x4 antennas on each band. Currently, mt7996 only supports tri-band HE or older mode. EHT mode and more variants of Filogic 680 support will be introduced in further patches.
