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