Unrecoverable advertisement/discovery errors on Kevin

Project Member Reported by khorimoto@chromium.org, Feb 28 2018 
Kevin: CrOS 10446.0.0, Chrome 66.0.3357.0

I left an Instant Tethering scan w/ 4 devices active. Eventually it hits an unending stream of BLE advertisement and BLE discovery errors.

Note that Kevin does NOT use an Intel chip for Bluetooth, so this is not b/69529500.

Kevin chip info (via go/crconn): Marvell MVL 8997 Marvell 8997 Azurewave

Dmitry could you take a look at this?

Comment 3 by khorimoto@chromium.org, Apr 2 2018 

Hi Dmitry - friendly ping :). Do you think you can get this issue triaged? If this is a firmware issue, I'd like to reach out to Marvell ASAP to get their team on it. Our other firmware issues have taken a long time to get done, so I'd like to get a head start on this issue.

I could help take a look today. It seems to me that it is the controller issue. Will post more details later.

This is the underlying controller/firmware issue. I think we need to have Marvell take a look ASAP.

--- more details below ---

There were continuous "tx timeout" errors starting at 

2018-02-28T14:54:16.098908-08:00 ERR kernel: [  501.388865] Bluetooth: hci_core.c:hci_cmd_timeout() hci0 command 0x2016 tx timeout

Looking at the btsnoop log, the "Set Advertising Data" HCI command never got a reply from the underlying controller.

< HCI Command: LE Set Advertising Data (0x08|0x0008) plen 32                                                                        #42340 [hci0] 2018-03-01 06:54:16.098016

After 2-second timeout, kernel tried again and again to resend the command. The controller failed to respond thereafter.
