+A new style for the model option that was introduced since 5.15 kernel

+where XXXX and YYYY are the sub-vendor and sub-device IDs in hex

----------------------------
The previous patch allowed user to specify the aliasing of SSID via model option for applying a quirk. Update the documentation accordingly.
