635 * specific STA information is accessed through @deflink or through
636 * link[0] which points to address of @deflink. For MLO Link STA
637 * the first added link STA will point to deflink.
638 * @link: reference to Link Sta entries. For Non MLO STA, except 1st link,
639 * i.e link[0] all links would be assigned to NULL by default and
640 * would access link information via @deflink or link[0]. For MLO
641 * STA, first link STA being added will point its link pointer to
642 * @deflink address and remaining would be allocated and the address
643 * would be assigned to link[link_id] where link_id is the id assigned
644 * by the AP.
