* Importing r401 of ported wlan stack from osdrawer.net/haiku-wifi.

Browse Source 
This port is based on FreeBSD RELEASE_8_0_0 (r199625) found in Haiku's
  freebsd vendor branch.
* Added freebsd_wlan directory to the Jamfile in HAIKU_TOP/src/libs/compat/
  so that the stack can be built with jam libfreebsd_wlan.a.

* Parameters for controlling a scan requested with

*
* Active scans cause ProbeRequest frames to be issued for each
* specified ssid and, by default, a broadcast ProbeRequest frame.
* The set of ssid's is specified in the request.
*
* By default the scan will cause a BSS to be joined (in station/adhoc
* mode) or a channel to be selected for operation (hostap mode).
* To disable that specify IEEE80211_IOC_SCAN_NOPICK and if the
*
* If the station is currently associated to an AP then a scan request
* will cause the station to leave the current channel and potentially
* miss frames from the AP. Alternatively the station may notify the
* AP that it is going into power save mode before it leaves the channel.
* This ensures frames for the station are buffered by the AP. This is
* termed a ``bg scan'' and is requested with the IEEE80211_IOC_SCAN_BGSCAN
* flag. Background scans may take longer than foreground scans and may
* be preempted by traffic. If a station is not associated to an AP
* then a request for a background scan is automatically done in the
* foreground.
*
* The results of the scan request are cached by the system. This
* information is aged out and/or invalidated based on events like not
* being able to associated to an AP. To flush the current cache
* contents before doing a scan the IEEE80211_IOC_SCAN_FLUSH flag may
* be specified.
*
* By default the scan will be done until a suitable AP is located
* or a channel is found for use. A scan can also be constrained
* to be done once (IEEE80211_IOC_SCAN_ONCE) or to last for no more
* than a specified duration.

* Virtual AP cloning parameters. The parent device must

*
* There are two flavors of WDS vaps: legacy and dynamic.
* Legacy WDS operation implements a static binding between
* two stations encapsulating traffic in 4-address frames.
* Dynamic WDS vaps are created when a station associates to
* an AP and sends a 4-address frame. If the AP vap is
* configured to support WDS then this will generate an
* event to user programs listening on the routing socket
* and a Dynamic WDS vap will be created to handle traffic
* to/from that station. In both cases the bssid of the
* peer must be specified when creating the vap.
*
* By default a vap will inherit the mac address/bssid of
* the underlying device. To request a unique address the
* IEEE80211_CLONE_BSSID flag should be supplied. This is
* meaningless for WDS vaps as they share the bssid of an
* AP vap that must otherwise exist. Note that some devices
* may not be able to support multiple addresses.
*
* Station mode vap's normally depend on the device to notice
* when the AP stops sending beacon frames. If IEEE80211_CLONE_NOBEACONS
* is specified the net80211 layer will do this in s/w. This
* is mostly useful when setting up a WDS repeater/extender where
* an AP vap is combined with a sta vap and the device isn't able
* to track beacon frames in hardware.

/*
* 802.11 scanning support.
*
* Scanning is the procedure by which a station locates a bss to join
* (infrastructure/ibss mode), or a channel to use (when operating as
* an ap or ibss master). Scans are either "active" or "passive". An
* active scan causes one or more probe request frames to be sent on
* visiting each channel. A passive request causes each channel in the
* scan set to be visited but no frames to be transmitted; the station
* only listens for traffic. Note that active scanning may still need
* to listen for traffic before sending probe request frames depending
* on regulatory constraints; the 802.11 layer handles this by generating
* a callback when scanning on a ``passive channel'' when the
* IEEE80211_FEXT_PROBECHAN flag is set.
*
* A scan operation involves constructing a set of channels to inspect
* (the scan set), visiting each channel and collecting information
* (e.g. what bss are present), and then analyzing the results to make
* decisions like which bss to join. This process needs to be as fast
* as possible so we do things like intelligently construct scan sets
* and dwell on a channel only as long as necessary. The scan code also
* maintains a cache of recent scan results and uses it to bypass scanning
* whenever possible. The scan cache is also used to enable roaming
* between access points when operating in infrastructure mode.
*
* Scanning is handled with pluggable modules that implement "policy"
* per-operating mode. The core scanning support provides an
* instrastructure to support these modules and exports a common api
* to the rest of the 802.11 layer. Policy modules decide what
* channels to visit, what state to record to make decisions (e.g. ap
* mode scanning for auto channel selection keeps significantly less
* state than sta mode scanning for an ap to associate to), and selects
* the final station/channel to return as the result of a scan.
*
* Scanning is done synchronously when initially bringing a vap to an
* operational state and optionally in the background to maintain the
* scan cache for doing roaming and rogue ap monitoring. Scanning is
* not tied to the 802.11 state machine that governs vaps though there
* is linkage to the IEEE80211_SCAN state. Only one vap at a time may
* be scanning; this scheduling policy is handled in ieee80211_new_state
* and is invisible to the scanning code.

* External authenticator placeholder module.
*
* This support is optional; it is only used when the 802.11 layer's
* authentication mode is set to use 802.1x or WPA is enabled separately
* (for WPA-PSK). If compiled as a module this code does not need
* to be present unless 802.1x/WPA is in use.
*
* The authenticator hooks into the 802.11 layer. At present we use none
* of the available callbacks--the user mode authenticator process works
* entirely from messages about stations joining and leaving.
