ieee80211_input, ieee80211_decap, ieee80211_recv_mgmt -- software 802.11
stack input functions
ieee80211_input(struct ieee80211com *ic, struct mbuf *m,
struct ieee80211_node *ni, int rssi, u_int32_t rstamp);
struct mbuf *
ieee80211_decap(struct ieee80211com *ic, struct mbuf *m);
ieee80211_recv_mgmt(struct ieee80211com *ic, struct mbuf *m0,
struct ieee80211_node *ni, int subtype, int rssi, u_int32_t rstamp);
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 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 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 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().
The ieee80211 series of functions first appeared in NetBSD 1.5, and were
later ported to FreeBSD 4.6.

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