These functions process received 802.11 frames.
The ieee80211_input() function takes an mbuf chain m containing a com-
plete 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 record-
ing 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().
The ieee80211 series of functions first appeared in NetBSD 1.5, and were
later ported to FreeBSD 4.6 and OpenBSD 3.6.

There is no netisr queue specifically for the software 802.11 stack yet.
