Hi,

I don't have btmon atm, but I have attached log of `hcidump -X` while running
`hciconfig hci0 up` on 3.11:

    Error: Unsupported Feature or Parameter Value


If needed, I can also attach logs for 3.9 but it seems, that after applying
patch to solve Delete Stored Link Key on broadcom devices, something went wrong
on CSR. Also, binary dump is attached.
