These functions process received 802.11 frames.
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.
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_recv_mgmt() performs input
processing for 802.11 management frames. It is typically called from within
ieee80211 series of functions first
appeared in NetBSD 1.5, and were later ported to
FreeBSD 4.6 and OpenBSD
There is no netisr queue specifically for the software 802.11 stack yet.
