+.Sh DESCRIPTION
+These
+functions process received 802.11 frames.
+.Pp
+.\"
+The
+.Fn ieee80211_input
+function takes an mbuf chain
+.Fa m
+containing a complete 802.11 frame from the driver
+.Fa ifp
+and passes it to the software 802.11 stack for input processing.
+The
+.Fa ni
+argument specifies an instance of
+.Vt struct ieee80211_node
+(which may be driver-specific) representing the node from which the
+frame was received.
+The arguments
+.Fa rssi
+and
+.Fa stamp
+are typically derived from on-card data structures; they are used for
+recording the signal strength and time received of the frame respectively.
+.Pp
+.\"
+The
+.Fn ieee80211_decap
+function performs decapsulation of the 802.11 frame in the mbuf chain
+.Fa m
+received by the device
+.Fa ifp ,
+taking the form of the 802.11 address fields into account;
+the structure of 802.11 addresses vary according to the intended
+source and destination of the frame.
+It is typically called from within
+.Fn ieee80211_input .
+.Pp
+.\"
+The
+.Fn ieee80211_recv_mgmt
+performs input processing for 802.11 management frames.
+It is typically called from within
+.Fn ieee80211_input .
