I cannot take firmware files from a 3rd party. Also I don't follow the
WCN3990 firmware development so I can't really comment how that firmware
release works with different WCN3990 hardware, board files and/or
calibration data. But if you think that release should be submitted to
linux-firmware that's up to you.
