Firmware download on the WCN3988 sometimes fails and is retried:
Bluetooth: hci0: QCA TLV response size mismatch
Bluetooth: hci0: QCA Failed to request file: qca/apbtfw11.tlv (-84)
The vendor event answering the baudrate change command can arrive late
and is then taken as the response of the last firmware segment, which
waits for any vendor event. Its length is 2 instead of the expected 3:
< HCI Command: Vendor (0x3f|0x0000) plen 220 (last segment)
> HCI Event: Vendor (0xff) plen 2
92 01
Drop and wait for this event on the WCN3988.
