yet to be investigated circumstances. If that happens truncate to the number
of rates that the firmware supports.

- 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.
Much work done by: sam

MFC after: 4 weeks
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.
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
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.
Obtained from: OpenBSD
the 5GHz band.
o Enable 802.11a channels scanning for 2915ABG adapters.
o Fix a typo (negociated->negotiated).
With hints from NetBSD.

in an IBSS. Store ids directly into ieee80211_node's instead of managing
our own private association table. Idea and code by Sam Leffler.

MFC after: 5 days
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.
MFC after: 1 day
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.
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.
