3. Fixed low throughput issue for WPA3 SAE
4. Added driver change for WLAN throughput improvement on 8997 SoC
5. Updated README to recommend not to use WEP/TKIP for all chipsets
6. WCSWREL-180: Fix P2P test fail on kernel higher than L5.12
7. WCSWREL-156: kernel_write/kernel_read not allowed by drivers for L5.10 kernel GKI buildou
8. Alternative for pm_qos_add_request/pm_qos_remove_request
