Sam Leffler 339ccfb391 Hoist 802.11 encapsulation up into net80211: 
o call ieee80211_encap in ieee80211_start so frames passed down to drivers
  are already encapsulated
o remove ieee80211_encap calls in drivers
o fixup wi so it recreates the 802.3 head it requires from the 802.11
  header contents
o move fast-frame aggregation from ath to net80211 (conditional on
  IEEE80211_SUPPORT_SUPERG):
  - aggregation is now done in ieee80211_start; it is enabled when the
    packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames
    are held on a staging queue according to ieee80211_ffagemax
    (net.wlan.ffagemax) to wait for a frame to combine with
  - drivers must call back to age/flush the staging queue (ath does this
    on tx done, at swba, and on rx according to the state of the tx queues
    and/or the contents of the staging queue)
  - remove fast-frame-related data structures from ath
  - add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle
    per-node fast-frames state (we reuse 11n tx ampdu state)
o change ieee80211_encap calling convention to include an explicit vap
  so frames coming through a WDS vap are recognized w/o setting M_WDS

With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

/*
* Parameters for controlling a scan requested with
* IEEE80211_IOC_SCAN_REQ.
*
* 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.
