* When the insertion fails (sta_info_insert()) returns non-zero), the
* structure will have been freed by sta_info_insert()!
*
+ * sta entries are added by mac80211 when you establish a link with a
+ * peer. This means different things for the different type of interfaces
+ * we support. For a regular station this mean we add the AP sta when we
+ * receive an assocation response from the AP. For IBSS this occurs when
+ * we receive a probe response or a beacon from target IBSS network. For
+ * WDS we add the sta for the peer imediately upon device open. When using
+ * AP mode we add stations for each respective station upon request from
+ * userspace through nl80211.
+ *
* Because there are debugfs entries for each station, and adding those
* must be able to sleep, it is also possible to "pin" a station entry,
* that means it can be removed from the hash table but not be freed.
