If anyone has any objections, please let me know. ------------------ From: Chih-Kang Chang [ Upstream commit dbff9040587e9bd6d3ee337315971957f9f76612 ] Only the WiFi 6 chips need to initialize RF register when WoWLAN download FW for some power save issue. Applying the same initialization flow to WiFi 7 chips might trigger the error 'RF parameters exceed size. path=1, idx=1500.'. This happens because normal mode uses rtw89_phy_config_rf_reg_v1(), which skips registers with addresses below 0x100. However, WoWLAN mode uses rtw89_phy_config_rf_reg_noio(), and WiFi 7 chips do not satisfy the rtw89_chip_rf_v1() condition. As a result, more RF registers are configured, causing the size overflow error.
