NAME

     ieee80211_input, ieee80211_decap, ieee80211_recv_mgmt -- software 802.11
     stack input functions


SYNOPSIS

     #include <net80211/ieee80211_var.h>
     #include <net80211/ieee80211_proto.h>

     void
     ieee80211_input(struct ieee80211com *ic, struct mbuf *m,
         struct ieee80211_node *ni, int rssi, u_int32_t rstamp);

     struct mbuf *
     ieee80211_decap(struct ieee80211com *ic, struct mbuf *m);

     void
     ieee80211_recv_mgmt(struct ieee80211com *ic, struct mbuf *m0,
         struct ieee80211_node *ni, int subtype, int rssi, u_int32_t rstamp);


DESCRIPTION

     These functions process received 802.11 frames.

     The ieee80211_input() function takes an mbuf chain m containing a com-
     plete 802.11 frame from the driver ic and passes it to the software
     802.11 stack for input processing.  The ni argument specifies an instance
     of 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 record-
     ing 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 ic, 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().

HISTORY

     The ieee80211 series of functions first appeared in NetBSD 1.5, and were
     later ported to FreeBSD 4.6.
