4982d693ac Add support to export the contents of the notification updates from the firmware.
Right now the NIC isn't actually exporting useful data. I'm not quite sure
why this is. :(

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.

aaae09da87 net80211 seems to give us more rates than specified via ic_sup_rates under
yet to be investigated circumstances. If that happens truncate to the number
of rates that the firmware supports.

c10b140011 MFp4: reworked iwi-driver
Changelog towards if_iwi.c 1.26 (some changes have been committed separately
in the mean time):

- add led support
- add firmware loading on demand
 - auto-restart firmware when it crashes
 - serialize operations sent to the firmware to reduce firmware crashes
- add power save operation support
 - remove incorrect specification of tx power control capability
- add radio on/off switch support

- improve net80211 state machine operation
 - recognize and handle beacon miss
 - handle authentication and association failures better
 - add shared key authentication
 - fix ibss mode (many changes)
 - fix wme (many changes)
- correct radiotap support (many changes)
- correct bus dma setup of s/g
- correct various locking issues
- fix monitor mode
- fix scanning (many changes)
 - recover from wedged scan requests
 - respect active channel list
- eliminate cases where interface was marked down on error
- don't treat parity errors as fatal
- reclaim mgt frames immediately from tx queue
- correct interrupt handling, ack early (from NetBSD)
- fix short/long preamble handling

Committed with RELENG_6 compat #if's, should compile in RELENG_6.  Requires
net/iwi-firmware-kmod to function.

389fb0b432 o acknowledge interrupts early in the interrupt handler
o stop processing interrupts after a firmware fatal error or a radio kill
o clarify the possible values for the 'antenna' sysctl.
o by default, let the firmware do antenna diversity.
  the  firmware will periodically switch to another antenna to evaluate the
  signal quality.

84f55b29e9 o Re-enable scatter/gather
o Change MEM_READ_1/MEM_READ_4 into macros (move them to if_iwireg.h)
o Add support for association LED
o Silently discard f/w notifications that are unknown (fixes spurious
  "unknown notification 15" in logs with latest firmware)
o Fix scanning of 5GHz channels

408146ed57 Load firmware images directly from the filesystem (looks into /etc/firmware
directory by default) without requiring the user to load them by hand using
e.g iwicontrol.  Get rid of the old ioctl crud.
Updated iwi-firmware port coming soon.

80e1a7127f o Use firmware extended scan command; this one doesn't crash when scanning
the 5GHz band.
o Enable 802.11a channels scanning for 2915ABG adapters.
o Fix a typo (negociated->negotiated).

With hints from NetBSD.

28a380736d Use phk's kernel unit number allocator to associate unique ids to neighbors
in an IBSS.  Store ids directly into ieee80211_node's instead of managing
our own private association table.  Idea and code by Sam Leffler.

0b74a28506 o Add initial bits for IBSS support.
o Allow association with APs that do not broadcast SSID (with hints from
  Nick Hudson and Hajimu Umemoto).
o IFQ_DRV_PREPEND mbuf when h/w ring is full so it can be sent later.
o Increment if_oerrors when appropriate.
o Did some cleanup while I'm here.

fb533d55c6 Enhanced WME (802.11e) support. 2005-08-21 09:52:18 +00:00
Damien Bergamini
ec01dc2bbc Add some necessary bits for upcoming 802.11e support:
o management of multiple tx rings (up to 4)
o setting of WME IE in association requests

Some features are still missing though, like the possibility to override
the default cwmin/cwmax/asfn values of each tx queues.

acea42415f o Clear device-specific PCI register 0x41 (Retry Timeout) during attach
and on resume (reported to fix issues with ACPI)
o Add monitor mode support
o Add WPA (802.11i) support (not tested extensively though!)
o Add a device specific sysctl to control the tx antenna (default to
  antenna diversity)
o Fix sensitivity setting
o Fix setting of the capinfo field when associating
o Temporarly disable 802.11a channels scanning that was causing firmware
  panics with 2915ABG adapters until I find a better fix.  This breaks
  802.11a support.
o Temporarly switch back to software WEP until I implement hardware
  encryption for AES and TKIP too.
