The NL80211_CMD_TDLS_OPER command was previously used only for userspace request for the kernel code to perform TDLS operations. However, there are also cases where the driver may need to request operations from userspace, e.g., when using security on the AP path. Add a new cfg80211 function for generating a TDLS operation event for drivers to request a new link to be set up (NL80211_TDLS_SETUP) or an existing link to be torn down (NL80211_TDLS_TEARDOWN). Drivers can optionally use these events, e.g., based on noticing data traffic being sent to a peer station that is seen with good signal strength.
