The TDLS link itself is bidirectional, but there is explicit initiator/responder roles. Remove the other direction of the link if it exists when processing TDLS Setup Confirm to make sure that the link counters are stored for the current TDLS entery. This is also changing the control interface search for TDLS counters to require initiator/responder addresses in the correct order instead of matching entries regardless of the role.
