A station table entry represents a station we are possibly
communicating with. Since stations are RCU-managed in
mac80211, any ieee80211_sta pointer you get access to must
either be protected by <code class="function">rcu_read_lock</code> explicitly or implicitly,
or you must take good care to not use such a pointer after a
call to your sta_remove callback that removed it.
