Public bug reported:

== Impact ==
The Bluetooth LED of Marvell 88W8897 is not enabled by default (there's no code 
for controlling LED). It is requested to be ON and OFF when the radio is on and 
off accordingly.

== Fix ==
The LEDs are connected to GPIO pins on the Marvell WiFi/Bluetooth combo module, 
thus they can only be controlled via firmware.

== Test Case ==
# hciconfig hci0 [on|off]
and see if the LEDs work properly.

== Risk of Regression ==
PCI sub IDs of the host bridge are used to determine if we're really running on 
an Edge Gateway, and we already have these patches in Xenial kernels quite a 
while. Risk should be reasonably low.
