Hi Daniel,
> This patch adds the 0cf3:e500 Bluetooth device (from a QCA9377 board) as a
> QCA_ROME device. It appears to be functionally identical to another device
> ID, also from a QCA9377 board, which was previously marked as QCA_ROME in
> 0a03f98b98c201191e3ba15a0e33f46d8660e1fd
> ("Bluetooth: Add a new 04ca:3015 QCA_ROME device").
>
> Without this patch, the WiFi side of the QCA9377 board is slow or unusable
> when the Bluetooth side is in use.
>
> See https://askubuntu.com/a/1137852 for another report of QCA_ROME fixing
> this issue for this device ID.
