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.
This can be used by external programs (e.g., wlantest_cli) to inject
raw frames (hex dump of the frame header and body). The data can be
requested to be sent as-is or protected with the current key.
This adds new commands for wlantest_cli to request wlantest to
inject frames. This version can only send out Authentication
frames and unprotected SA Query Request frames, but there is
now place to add more frames and encryption with future commits.
