Add modes for 1/2 and 1/4-width channels so we have separate roaming
and xmit parameters. This makes it possible to use tdma on fractional
channels.
o add IEEE80211_MODE_HALF and IEEE80211_MODE_QUARTER; note these are
band-agnostic (may need revisiting)
o setup all default rates in ic_sup_rates instead of doing it only
for active modes; we need these to calculate the default tx parameters
which are not recalculated after a regulatory update (can't just
recalculate after installing a new channel list because we might
clobber user settings)
o remove special case code in ieee80211_get_suprates; this is now
a candidate for an inline or removal
o add various entries for new modes (roaming+tx params, wme, rate
mapping, scan set setup, country ie construction, tdma, basic rates)

Note these modes are intentionally not visible through if_media.

simplify setting up the roaming parameters; writing default parameters only
for active modes hasn't turned out to be useful so just define a const table
and copy it in place

convert MALLOC/FREE to malloc/free

Revert the removal of the MALLOC and FREE macros from the net80211 code.

Retire the MALLOC and FREE macros. They are an abomination unto style(9).

Multi-bss (aka vap) support for 802.11 devices.

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now
bundled into the wlan module.

Fix scanning issues since the new net80211 code went in
- provide dummy routines for ic_scan_curchan and ic_scan_mindwell, we do not support those operations.
- add ieee80211_scan_done() to tell the scanning module that all channels have been scanned.
- pass IEEE80211_S_SCAN state off to net80211 so it can initiate scanning
- fix overflow in the rates array
- scale the rate value passed back from the firmware scan to the units that net80211 uses.

Change the channel number in the scan results struct to be a pointer to the
operating channel and use this in the scan cache rather than directly using
ic_curchan. Some firmware cards can only do a full scan and so ic_curchan does
not have the correct value.

Also add IEEE80211_CHAN2IEEE to directly dereference ic_ieee from the channel
to be used in the fast path.

Update 802.11 wireless support:
o major overhaul of the way channels are handled: channels are now
fully enumerated and uniquely identify the operating characteristics;
these changes are visible to user applications which require changes
o make scanning support independent of the state machine to enable
background scanning and roaming
o move scanning support into loadable modules based on the operating
mode to enable different policies and reduce the memory footprint
on systems w/ constrained resources
o add background scanning in station mode (no support for adhoc/ibss
mode yet)
o significantly speedup sta mode scanning with a variety of techniques
o add roaming support when background scanning is supported; for now
we use a simple algorithm to trigger a roam: we threshold the rssi
and tx rate, if either drops too low we try to roam to a new ap
o add tx fragmentation support
o add first cut at 802.11n support: this code works with forthcoming
drivers but is incomplete; it's included now to establish a baseline
for other drivers to be developed and for user applications
o adjust max_linkhdr et. al. to reflect 802.11 requirements; this eliminates
prepending mbufs for traffic generated locally
o add support for Atheros protocol extensions; mainly the fast frames
encapsulation (note this can be used with any card that can tx+rx
large frames correctly)
o add sta support for ap's that beacon both WPA1+2 support
o change all data types from bsd-style to posix-style
o propagate noise floor data from drivers to net80211 and on to user apps
o correct various issues in the sta mode state machine related to handling
authentication and association failures
o enable the addition of sta mode power save support for drivers that need
net80211 support (not in this commit)
o remove old WI compatibility ioctls (wicontrol is officially dead)
o change the data structures returned for get sta info and get scan
results so future additions will not break user apps
o fixed tx rate is now maintained internally as an ieee rate and not an
index into the rate set; this needs to be extended to deal with
multi-mode operation
o add extended channel specifications to radiotap to enable 11n sniffing

Drivers:
o ath: add support for bg scanning, tx fragmentation, fast frames,
dynamic turbo (lightly tested), 11n (sniffing only and needs
new hal)
o awi: compile tested only
o ndis: lightly tested
o ipw: lightly tested
o iwi: add support for bg scanning (well tested but may have some
rough edges)
o ral, ural, rum: add suppoort for bg scanning, calibrate rssi data
o wi: lightly tested

This work is based on contributions by Atheros, kmacy, sephe, thompsa,
mlaier, kevlo, and others. Much of the scanning work was supported by
Atheros. The 11n work was supported by Marvell.
