Subject: [PATCH] Remove duplicated code from ipw2200.c

As stated in a comment, the ipw2200 driver uses several routines that
were borrowed from ieee80211_geo.c. As ipw2200 requires ieee80211,
these routines are duplicated. The attached patch, which is sent
as an attachment to preserve whitespace, converts ipw2200.c to use
the ieee80211 versions, thereby reducing bloat in both the source
and binary.

Subject: [PATCH] ipw2200: print geography code upon module load

Given the amount of support requests for the meaning of the geography code
I've written a patch for printing this information on module load no matter
the debug level.

I've also added a section to the README.ipw2200 file listing the geography
codes and their meaning.

Subject: [PATCH] ipw2200: stop netdev queue if h/w doesn't have space for new
 packets

The patch roll back the change we made to support for the ability to
start/stop independent Tx queues within a single net device in order to
support 802.11e QoS. We need to be able to indicate to the upper layers
that packets of a given priority can not be sent any more without halting
transmission of all packets, and without rescheduling high priority packets
down to the next priority level.

So we return NETDEV_TX_BUSY in this case and rely on the stack would
take care of rescheduling... which it apparently does immediately and
consumes the CPU. This caused the ksoftirqd kernel thread consuming almost
all the CPU...

To put the code back to the way it was before we made these changes we
put the call netif_queue_stop back in ipw_tx_skb.  This effectively
disables multiple priority based transmit queues for 802.11e, but given
that its broken anyway...

Subject: [PATCH] ipw2200: Add signal level to iwlist scan output

This patch does two things. It uses the parameter IW_QUAL_DBM which is new
in WE-19 to cause signal level and noise to be reported in dBm by the
wireless tools. It also defines the signal level as an unsigned integer
so that the signal level will be reported by iwlist iface scan.

Subject: [PATCH] ipw2200: Fix rf_kill is activated after mode change with
 'disable=1'

When loading the ipw2200 module with disabled=1, rf_kill is activated after
every mode change. This is caused by ipw_sw_reset() is called when a mode
is changed. The patch fixed the problem by distinguishing the purposes with
the 'option' paramenter.

Subject: [PATCH] ipw2200: Set a meaningful silence threshold value

Set a meaningful silence threshold value (replacing our previous "0"
default), which gets rid of the gratuitous "Link deterioration"
notifications that we've been receiving from firmware.  This
notification feature tells the driver information to help it determine
when to pre-emptively restart the firmware/ucode in anticipation of
firmware errors!  But since setting this new threshold, I haven't seen
any such notifications.  At least it keeps the logs a little less busy.

From 9006ea75cfaded82acbc34d03e9d4e86447f40a9 Mon Sep 17 00:00:00 2001
From: James Ketrenos <jketreno@linux.intel.com>
Date: Wed, 8 Mar 2006 03:22:28 +0800
Subject: [PATCH] ipw2200: switch to the new ipw2200-fw-3.0 image format

This patch modifies the driver to support the ipw2200-fw-3.0 image format.

The 3.0 fw image does not add any new capabilities, but as a result of
image format changes, it should fix two problems experienced by users:

1) Race conditions with the request_firmware interface and udev/hotplug
are improved as only a single request_firmware call is now required to
load the firmware and microcode (vs. 3 separate calls previously)

2) The monitor mode firmware (sniffer) is now packaged with the correct
boot image so it can now function without frequent restarts.

Note: Once you apply this patch, you will also need to upgrade your
firmware image to the 3.0 version available from:

        http://ipw2200.sf.net/firmware.php
