TDLS: Tear down peers when disconnecting from the AP
A TDLS Teardown frame with Reason Code 3 (Deauthenticated because sending STA is leaving (or has left) IBSS or ESS) shall be transmitted to all TDLS peer STAs (via the AP or via the direct path) prior to transmitting a Disassociation frame or a Deauthentication frame to the AP.
