Thanks for the feedback. This is a special case that the ODM didn't
flash the DMI information
and assign a formal SSID. They simply ship with the current status w/o

I agree that we should push the vendor for a BIOS fix or figure out a
generic solution for this
instead of a pin quirk. Please ignore this. Thanks

Chris
