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 ifnet *ifp, struct mbuf *m,
        struct   ieee80211_node  *ni,  int  rssi,  u_int32_t
rstamp);
struct mbuf *
ieee80211_decap(struct ifnet *ifp, 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 con

taining a complete 802.11 frame from the driver ifp and passes it to the

software
802.11 stack for input processing. The ni argument speci

fies an instance
of struct ieee80211_node (which may be driver-specific) rep

resenting 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 re

spectively.

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().

HISTORY

The ieee80211 series of functions first appeared in NetBSD

1.5, and were
later ported to FreeBSD 4.6.
