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)
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
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().

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