spe_idx is also needed for fixed rate frames, and will be updated by

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.
