DESCRIPTION

These functions process received 802.11 frames.

The ieee80211_input function takes an mbuf chain m containing a complete 802.11 frame from the driver ifp and passes it to the software 802.11 stack for input processing. The 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 rssi and stamp are typically derived from on-card data structures; they are used for recording the signal strength and time received of the frame respectively.

The ieee80211_decap function performs decapsulation of the 802.11 frame in the mbuf chain m received by the device 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 ieee80211_input.

The ieee80211_recv_mgmt performs input processing for 802.11 management frames. It is typically called from within ieee80211_input.
