    NAME

    
    
    ieee80211_input , ieee80211_decap , ieee80211_recv_mgmt
    
     - software 802.11 stack input functions
    
     
    

    SYNOPSIS

    DESCRIPTION

    These functions process received 802.11 frames.

    The 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.

    The 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 ieee80211_input (.);

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