.SH "DESCRIPTION"
.PP
.PP
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
\fBrcu_read_lock\fR
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\&.
