I think that I said this before. Why do you think that adding a new
socket option to something called _old is a good idea? I made it pretty
clear in the code that it is an OLD interface.
I want this on the SOL_BLUETOOTH level with a proper new socket option.
And we might even consider doing it like BT_SECURITY where create the
struct to potentially add other flags later.
So why not doing BT_POWER or something like that.
And in addition you need to store these values on a per L2CAP or RFCOMM
socket. You can not just go ahead and mess inside hci_conn via an L2CAP
socket option.

Marcel

This can be done.

I felt that Sniff Mode is a property of ACL link and not L2CAP or RFCOMM so=
cket.
There is already code in the same functions which use the same
technique to access
following hci_conn fields:
l2cap_pi(sk)->conn->hcon->handle
l2cap_pi(sk)->conn->hcon->dev_class
