.Sh DESCRIPTION
|
|
These
|
|
functions process received 802.11 frames.
|
|
.Pp
|
|
.\"
|
|
The
|
|
.Fn ieee80211_input
|
|
function takes an mbuf chain
|
|
.Fa m
|
|
containing a complete 802.11 frame from the driver
|
|
.Fa ifp
|
|
and passes it to the software 802.11 stack for input processing.
|
|
The
|
|
.Fa ni
|
|
argument specifies an instance of
|
|
.Vt struct ieee80211_node
|
|
(which may be driver-specific) representing the node from which the
|
|
frame was received.
|
|
The arguments
|
|
.Fa rssi
|
|
and
|
|
.Fa stamp
|
|
are typically derived from on-card data structures; they are used for
|
|
recording the signal strength and time received of the frame respectively.
|
|
.Pp
|
|
.\"
|
|
The
|
|
.Fn ieee80211_decap
|
|
function performs decapsulation of the 802.11 frame in the mbuf chain
|
|
.Fa m
|
|
received by the device
|
|
.Fa 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

|
|
The
|
|
.Fn ieee80211_recv_mgmt
|
|
performs input processing for 802.11 management frames.
|
