FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

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 containing a com‐
      plete 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 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 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().
      ieee80211(9), ifnet(9)
 

HISTORY

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

Sections

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
