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 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 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 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 and OpenBSD
3.6.
