This patch enables the ipw2200 driver to support passive scanning as
offered by the wireless extensions. For this, I enhanced the ipw_wx_set_scan
function in such a way that it differentiates between a passive and an
active scan request. Additionally, I added a new function called
ipw_request_passive_scan that is similiar to the ipw_request_scan
function to perform passive scans. Last but not least, I added a field
(in fact it is a work_struct struct) called request_passive_scan to
the ipw_priv struct.

This patch cleanups the ipw_wx_set_essid code and forces a reassociation
when setting the essid to "any". I have tested this patch with iwconfig. It
makes ipw2200 compliant with all the cases mentioned in the iwconfig man
page. The commands
iwconfig iface essid any
iwconfig iface essid -- any
iwconfig iface essid off
iwconfig iface essid on
all seemed to work correctly. None of this worked before the patch.
Note, this patch treats
iwconfig iface essid
iwconfig iface essid ""
The same. It produces an error message: essid: Unknown host.

The SIOCGIWFREQ ioctl fills the request structure's freq field by setting
the exponent to 0 and the mantissa to the current channel number. The
iwconfig tool works around this behaviour by looking up the frequency
from the channel table if a frequency below 1kHz is returned, other tools
(e.g. kwlaninfo) don't. According to the comment in the iwconfig source
the driver is supposed to return the frequency, not the channel number.

With this patch, a new promiscuous mode is enabled. If the module is loaded
with the rtap_iface=1 module parameter, two interfaces will be created
(instead of just one).
The second interface is prefixed 'rtap' and provides received 802.11 frames
on the current channel to user space in a radiotap header format.
Example usage:
% modprobe ipw2200 rtap_iface=1
% iwconfig eth1 essid MyNetwork
% dhcpcd eth1
% tcpdump -i rtap0
If you do not specify 'rtap_iface=1' then the rtap interface will
not be created and you will need to turn it on via:
% echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
You can filter out what type of information is passed to user space via
the rtap_filter sysfs entry. Currently you can tell the driver to
transmit just the headers (which will provide the RADIOTAP and IEEE
802.11 header but not the payload), to filter based on frame control
type (Management, Control, or Data), and whether to report transmitted
frames, received frames, or both.
The transmit frame reporting is based on a patch by Stefan Rompf.
Filters can be get and set via a sysfs interface. For example, set the
filter to only send headers (0x7), don't report Tx'd frames (0x10), and
don't report data frames (0x100):
% echo 0x117 > /sys/bus/pci/drivers/ipw2200/*/rtap_filter
All your packets are belong to us:
% tethereal -n -i rtap0

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:

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...

Checking the stack usage of my kernel, showed that ipw2200 had a few bad
offenders. This is on i386 32-bit:
0x00002876 ipw_send_associate: 544
0x000028ee ipw_send_associate: 544
0x000027dc ipw_send_scan_request_ext: 520
0x00002864 ipw_set_sensitivity: 520
0x00005eac ipw_set_rsn_capa: 520
The reason is the host_cmd structure is large (500 bytes). All other
functions currently using ipw_send_cmd() suffer from the same problem.
This patch introduces ipw_send_cmd_simple() for commands with no data
transfer, and ipw_send_cmd_pdu() for commands with a data payload and
makes the payload a pointer to the buffer passed in from the caller.
As an added bonus, the diffstat looks like this:
ipw2200.c | 260 +++++++++++++++++++++-----------------------------------------
ipw2200.h | 2
2 files changed, 92 insertions(+), 170 deletions(-)
and it shrinks the module a lot as well:

After:

I can't really help with why restarts happen, but the following patch
greatly increases the likelihood that a firmware reload will succeed
afterward on my thinkpad. It addresses two issues. First, sysfs module
loading and hotplug are asynchronous, and as such file operations on the
"loading" and "data" files are racy when you load 2 firmwares in quick
succession. Second, the timeout for DMAing the firmware needs to scale
with the size of the firmware being loaded. That is, the watchdog needs
to be on throughput, not on time alone.
I no longer get the firmware load errors, though this is at best a hacky
workaround for a racy interface. (Obviously, this does nothing to address
the fatal errors in firmware which cause reloads; it just causes the
initial loading and the reloads to work more often.)

The problem is caused by the patch in bug455 -- Channel change flood
generates fatal error.
The patch set the DISASSOCIATING status bit after sending the command.

Move the bit setting code before sending the command now.
