From: Johan Hedberg <johan.hedberg@xxxxxxxxx>
Some counterfeit CSR controllers also have broken behavior with the
HCI_Read_Stored_Link_Key command:
< HCI Command: Read Stored Link Key (0x03|0x000d) plen 7
Address: 00:00:00:00:00:00 (OUI 00-00-00)
Read all: 0x01
> HCI Event: Command Complete (0x0e) plen 8
Read Stored Link Key (0x03|0x000d) ncmd 1
Status: Unsupported Feature or Parameter Value (0x11)
Max num keys: 0
Num keys: 0
Extend the existing HCI_QUIRK_BROKEN_STORED_LINK_KEY to be also used
for this HCI command.
