It requires updated firmwares to enable it.

[Test Case]
After applying the required firmwares, it can search APs and connect to the network.

[Regression Potential]
Although the new firmware overwrite the old one, considering it exists in linux-firmware git tree and didn't get any update for 3 month, it should be good with no regression.
