 - Add a per frame rx structure for OOB data to be passed to p80211
	This is a step in the right direction for a major overhaul of 
	internal frame representation.  The prism2 driver shouldn't care 
	about sniff headers or any of that crap; it should always pass
	everything to p80211  (via this metadata) and the p80211conv_* 
	functions should do that work.  It's also needed to eventually
	support different encryption types.

  - Hopefully fix the 2.2.x build.
  - More USB fixes (Chris Rankin)
  - Compile fixes for < 2.4.20
-pre8
  - Fix the pcmcia breakage introduced in -pre2.

-pre7
  - Add in the 'JVC MP-XP7250" USB Widget.
  - Don't call ev_alloc on tx_complete event; only the tx urb completion.
  - Minor tweaks to tx_timeout code
  - More USB updates; primarily with error-handling.  (Chris Rankin) 
-pre6
  - On USB transmits, don't return 'success' if the tx_urb is still
    pending.  Also don't wake the netdev queue if the tx fails.
  - Hook up the tx watchdog timer and add a p80211-level handler.
  - Fix compilation with older (<= 2.4.18) kernels.
  - Another massive USB+other patch from Chris Rankin:
    - a separate list for "finished" CTLX objects.
    - correct (hopefully!) handling of -EPIPE errors, shamelessly copied
      from^W^Winspired by David Brownell's usbnet driver.
    - finished support for asynchronous commands, with proper tracking 
      through the CTLX lifecycle, clean-up etc. Each asynchronous command now 
      completes in its own tasklet.
    - CTLX cancellation and error handling.
    - further work on the timers and spin locks.
    - clean up setconfig16() and setconfig32() functions so that they 
      take appropriate value parameters, even if the underlying 
      setconfig() commands don't.
    - use an asynchronous command in setmulticast(). (CS, PCI and PLX 
      are still synchronous; they just pretend not to be.)
    - further clean up in the disconnect() handler. However, it's still 
      not a good idea to remove the adapter while the 
      prism2sta_inf_hostscanresults() function is sleeping, and the wlandevice
      struct could easily have been freed before the p80211req_dorequest() 
      function manages to clear the request_pending bit. It would be 
      nice if we could cancel both of these operations when we call 
      prism2sta_ifstate(P80211ENUM_ifstate_disable). 
    - extra support for Linux 2.5 (task queue -> work queue).
    - reset the link status when we stop the driver.
  - Some work on module locking.  Not there yet, but getting better.
  - Remove magic numbers from USB endpoint probe (Chris Rankin)
  - Eliminate useless timer in p80211do_request, as all calls are 
    synchronous.  Also clena up more function pointers, and a few other 
    doodads. (Modified from patch by Chris Rankin)
  - Track the current SSID in the wlandev; Make the WEXT stuff key from 
    this.  Update the SSID when we get a linkstatus_connect notification.
  - A couple of misc cleanups from Chris Wilson
  - Cleanups in the 2.5 makefile code. (Pavel Roskin)
  - Add in another PCI device ID, to handle Sony VAIO PCG-V505AP
  - Make sure CONFIG_ISA is enabled for the prism2_cs build. (x86 only)

    - separate callbacks for data/CTLX OUT URBs
    - flush task queue on shutdown
    - more thorough use of spinlocks with CTLXs
    - set the ASYNC_UNLINK flag when it is time to unlink an URB 
      asynchronously, and not before.
    - ensure we stop submitting URBs once the disconnect function 
      is called.
  - More USB idents (Jeff Chua)
  - Scan now uses active scans only; should speed things up a bit.
  - Proper module init/cleanup in prism2sta.c, plus more work for 2.5.69
  - Added in descriptions for module parameters.
  - Major overhaul of the hotplug stuff.  Now we use our own hotplug
    event class, and use that to kick off configuration and whatnot.
    All device types (pci/plx/pcmcia/usb) now use this mechanism.
    Also brings us things like unified power management (suspend/resume)
  - Supress spurious output when setting WEP parameters.
  - Only query PrivacyOptionImplemented if wep was enabled in the config

  - Add support for the new sniff frame capture. (doc/capturefrm.txt)
  - Get rid of some bitrot with the sniffing code.
  - Populate the tx dropped frames statistics.
-pre5
  - Fixes for host scan when not currently joined.
  - /proc support; some informational stuff is kept in /proc/wlandev/wlanX
  - Complete rewrite of the configuration files and startup scripts.
     hotplug(pci+usb), pcmcia, rc, everything uses same config file(s).
     per-network configuration
     supports scanning and automatically choosing a network from a set.
  - Fix the TMD7160/ncp130 support so it acually works.  :)
  - Make the BUG() call in cmd_access enabled only in debug builds.
  - Minor makefile fixes.
  - Microsoft MN520 PCMCIA ident info added.
  - p2cnfShortPreamble is not a boolean value.  (Clay Jones)
-pre4
  - BAP access fixes for PCI platforms.  This mostly affects SMP 
    arrangements.
  - Back out W200 USB ident info; it's not prism-based.
  - Patch from Tom Prado to make 'keygen' more user-friendly.
  - bap_timeout parameter only valid on non-usb platforms
-pre3
  - Added Ident info for the USB Compaq/Intel W200 widget
  - dot11req_scan requires firmware >=1.3.2.
  - Added the "Acer Warplink USB Adapter" id.
  - Rework the prism2sta_inf_linkstatus call to defer processing of
    results until outside interrupt context.  Should fix the SMP
    deadlocks seen on some machines.
  - Rework the usb_disconnect code to hopefully alleviate the occasional
    crash-on-disconnect some people see.  Solution is not SMP-safe yet.
  - Add the D-Link DCF-660W ident info.
-pre2
  - New parameter, 'prism2_bap_timeout' to specify the timeout on
    bap setup.  timeout*10 == timeout in microseconds.  Note that this
    timeout occurs in spinlock context, so increasing it arbitrarily is
    BAD!  Defaults to 1000, ie 10000us.  
  - compile fix for prism2sta in debug mode.
  - Only prompt for pcmcia sources if we're using non-kernel pcmcia.
    (original patch by Beat Bolli, rewritten a bit..)
  - Add the Linksys WCF12 CF ident info.
  - A bunch of compile fixes for older versions of wireless extensions.
  - Added implementations of GIWTXPOWER and GIWRETRY
  - Some fixes to the wireless extension code (thanks to Jean Tourrilhes)
-pre1
  - wland was incorrectly using kernel headers in its compile. 
  - Adhoc mode was auto-roaming onto "any" SSID.  Fixed.
  - Implemented the dot11req_scan & dot11req_scan_results functions.
      This, combined with more intelligent startup scripts, will allow
      you per-network profiles.   Scripts are unwritten as yet.  :)
  - hfa384x.h and MIB updates.
  - Rewrote the wireless extension support code; moved to p80211 layer.
      Now we're compatible with at least v6-v14, and everything
      inbetween.   We hook up to the new iw_request structure, which
      makes further wireless extension support much easier to add.
  - Add the Microsoft MN510 USB device ID.
  - Finally fix the 'crash on unload' problem for 2.2.x kernels with PCI.
    Turns out the kcompat24 code wasn't quite complete.  (Matthew Rush)
  - Cleaned up our usage of __FUNCTION__ to make gcc 3.x happy.
  - Fix a typo in the prism2 makefile.  
0.1.15
  - Fix an obscure PCMCIA build problem. (modversions disabled but
    header present, and using non-kernel pcmcia)
-pre8
  - Added code to optionally truncate packets in monitor mode. (Clay Jones)
  - Fix a polarity problem with the stripfcs argument to monitor mode.
  - Add a test to make sure wireless.h is included.
  - Netgear MA401A card ident.
  - Further cleanups of the build system (Makefiles)
-pre7
  - Include wireless.h so wireless extensions work again.  :)
  - Work around the braindead RedHat kernel build system.
  - Fix a class of unaligned accesses in the message structures 
    (kernel driver) and user space parsers (wlanctl-ng, etc)
  - Fix an unpacked struct problem that affected ARM platforms
    (thanks to Clay Jones for spotting this one)
-pre6
  - Support the new auto-unknown mode present in firmware >1.3.3
    When issuing an autojoin, we try to join a BSS, then an IBSS, and if
    all fails, we create a new IBSS with the given parameters. 
 	*note*  currently disabled.
  - Updates to hfa384x.h to reflect latest documentation
  - Build system mini-enema.  Automagically detect kernel version,
    pcmcia status, and modversions.  Pick up the kernel compile flags.
  - Hopefully fixed the 'crash on unload' for 2.2.x kernels and PCI.
  - 'p2req_join' command, see doc/wlanctl-ng.p2req_join.txt 
    This lets you join a specific SSID.  Thanks to Clay Jones.
  - A couple more pcmcia/cf card idents
  - More deletions/fixes in wlan_compat.h
-pre5
  - Due to new hotplug code, atmel device detection removed
  - Further cleanups in wlan_compat.h and non-kernel makefiles
  - Debian package stuff yanked in favor of the "official" deb packages
  - Rearranged the wireless extension support code a bit
  - A fix for the promisc/allmulti stuff on USB devices
-pre4
  - Hotplug support for PCI/PLX/USB widgets
  - A compile fix for 2.2.x (x < 18) kernels and PCI adapters
