IEEE80211_INPUT(9) BSD Kernel Developer's Manual IEEE80211_INPUT(9)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 complete 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) represent-
ing 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 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().

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

BUGS
There is no netisr queue specifically for the software 802.11 stack yet.

ieee80211_cfgget, ieee80211_cfgset, ieee80211_ioctl -- 802.11 interface ioctl commands
SYNOPSIS
#include <net80211/ieee80211_var.h>
#include <net80211/ieee80211_proto.h>
#include <net80211/ieee80211_ioctl.h>
int
ieee80211_cfgget(struct ieee80211com *ic, u_long cmd, void *data);
int
ieee80211_cfgset(struct ieee80211com *ic, u_long cmd, void *data);
int
ieee80211_ioctl(struct ieee80211com *ic, u_long cmd, void *data);
DESCRIPTION
These functions are typically invoked by drivers in response to requests for information or to change settings from the userland.
The ieee80211_cfgget() and ieee80211_cfgset() functions implement a legacy interface for getting and setting 802.11 interface attributes
respectively. The interface is compatible with the RIDs implemented by the wi(4) driver and used by the wiconfig(8) utility.
The ieee80211_ioctl() function implements ioctls such as key management for wireless devices. Ioctls related to the Ethernet layer also pass
through here, but are handed off to ether_ioctl() when no match for cmd is found.

Hello,
I have a log file which looks like this :
I want to cut out some text and get printed only : "HTTP GET" and "Time duration: 1013 mls. (1 sec.)" I tried searching the forum for such solution, but I was unable to find it.
I also tried awk '/duration/ { print $0 }' mylogfile.log,... (2 Replies)
I'm new to networking world. So please bear with me.
My Questions:
1. How do we send TCP/IP in a 802.3 frame? My understanding is that we have to incorporate the 802.3 LLC layer. The DSAP and SSAP in the LLC layer will provide information of the type of data inside the Information field of... (0 Replies)
I have only some info into my buffer, but after a rssi command I see the folowing lines expected into buffer but not present :
rssi=-106
