This\nallows the operation to proceed for non-TDLS stations, causing\nunintended side effects like modifying channel context and HT\nprotection before failing.\n\nAdd a check for sta->sta.tdls early in the ENABLE_LINK case, before\nany side effects occur, to ensure the operation is only allowed for\nactual TDLS peers."
