WCN6856 6G support was explicitly turned off in bug 1954938, making the commits porting to jammy meaningless. (And yet all the 6G support should have been in position in oem-5.17)
The "UBUNTU: SAUCE: Bluetooth: btusb: Add support using different nvm for variant WCN6855 controller", which is not related to WiFi 6G, has been committed separately in bug 1955689.
