If anyone has any objections, please let me know. ------------------ From: Kang Yang [ Upstream commit 04f33114af00317dc3c494e60a7c42292e0ffd7e ] Current struct hal_rx_phyrx_rssi_legacy_info in hal_rx.h is not matched with hardware descriptor definition. This hardware descriptor definition is determined by hardware. Host shall follow it. So update struct hal_rx_phyrx_rssi_legacy_info and related code. Both QCN9274 and WCN7850 need this modification.
