When idle, Marvell 88W8897 Bluetooth adapter sends the following
HCI vendor events to BlueZ stack on continuous basis:
$ btmon
Bluetooth monitor ver 5.43
= New Index: XX:XX:XX:XX:XX:XX (Primary,SDIO,hci0) [hci0] 0.029199
= Open Index: XX:XX:XX:XX:XX:XX [hci0] 0.029211
= Index Info: XX:XX:XX:XX:XX:XX (Marvell Technology Group Ltd.)
[hci0] 0.029222
> HCI Event: Vendor (0xff) plen 5 [hci0] 0.300944
05 80 00 09 00
> HCI Event: Vendor (0xff) plen 5 [hci0] 2.860113
05 80 00 09 00
> HCI Event: Vendor (0xff) plen 5 [hci0] 5.420643
05 80 00 09 00
...
Add -V option to suppress these HCI vendor events from btmon log.
