26d39e2c68 o add ic_rt to track the rate table for the current channel; this enables
calculation of packet transmit times to do things like check txop limits

6a76ae216e 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.

cbb24c240d o looseen abi dependencies on IEEE80211_MODE_MAX by accepting smaller
parameters for IEEE80211_IOC_ROAM and IEEE80211_IOC_TXPARAMS; this
  lets us add more modes and still have old apps work

ae55932e23 Add a ieee80211_waitfor_parent() function that will wait for all deferred
parent interface tasks to complete. This had been added to the ioctl path but
it is also need elsewhere like detach so its safe to teardown.

f8b1ea1737 add an assert to verify the number of channels returned by ic_getradiocaps

8658b18b82 Remove assumptions about the max # channels in ioctl's:
o change ioctl's that pass channel lists in/out to handle variable-size
  arrays instead of a fixed (compile-time) value; we do this in a way
  that maintains binary compatibility
o change ifconfig so all channel list data structures are now allocated
  to hold MAXCHAN entries (1536); this, for example, allows the kernel
  to return > IEEE80211_CHAN_MAX entries for calls like IEEE80211_IOC_DEVCAPS

8d9b29f35b If the parent up/down task was queued then sync with it before returning from
the vap ioctl. This means that the parent interface should hopefully be up
before we return to userland, it does not depend on the parent init succeeding,
just that it was run.

This fixes wpa_supplicant with ndis and USB where the parent interfaces can be
slow to init.

10ad9a77f3 TDMA support for long distance point-to-point links using ath devices:
o add net80211 support for a tdma vap that is built on top of the
  existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
  conceivable other devices might be capable of this too in which case
  they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
  configure, new statistics in athstats, and new debug mask bits

While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.

71fe06ca7f Add a mac address to the key definition as otherwise we lose the

to locate a key (e.g. for delete).

Note this changes net80211-private api's but not the driver callback;
may want to change that in the future.

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

68e8e04e93 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.

d1c85dae69 More statistics fixups:

o add noise floor in ieee80211_nodestats (use an implicit hole to

  so the driver can provide noise floor data
o add a bandaid so IEEE80211_IOC_STA_STATS works for sta mode; when
  all nodes are in the station table this will no longer be needed
o fix braino in IEEE80211_IOC_STA_INFO implementation; was supposed
  to take a mac address and return info for that sta or all stations

  implement the intended semantics and leave a compat shim at the old

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.
