The SPR parameter set comprises OBSS PD threshold for SRG and
non SRG and Bitmap of BSS color and partial BSSID. This adds
support to configure fields of SPR element to firmware.

User can disable firmware SR algorithms by turning sr_scene_detect off.

Shayne ChenandFelix Fietkau de3e77227f wifi: mt76: mt7996: add driver for MediaTek Wi-Fi 7 (802.11be) devices 
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.
