      Bluetooth: hci_bcm: Handle empty packet after firmware loading · 01d5e44a
      Marcel Holtmann authored
      The Broadcom controller on the Raspberry Pi3 sends an empty packet with
      packet type 0x00 after launching the firmware. This will cause logging
      of errors.
      
        Bluetooth: hci0: Frame reassembly failed (-84)
      
      Since this seems to be an intented behaviour of the controller, handle
      it gracefully by parsing that empty packet with packet type 0x00 and
      then just simply report it as diagnostic packet.
      
      With that change no errors are logging and the packet itself is actually
      recorded in the Bluetooth monitor traces.
