4b1f8a99a2 [PATCH] ipw2200: Add IEEE80211_RADIOTAP_TSFT for promiscuous mode
The ipw2200 BSS firmware passes on the TSF information within ipw_rx_frame,
but monitor firmware doesn't. I add back the IEEE80211_RADIOTAP_TSFT flags
so that we can get the MAC timestamp if we use the rtap interface. We will
see the MAC timestamp equals to zero if we capture the packets with a
monitor mode interface. But this is the expected behaviour.

7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

094c4d2df6 [PATCH] ipw2200: enable wireless extension passive scan
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 traps the case when the essid is being set to its

ab644b0b51 [PATCH] ipw2200: ipw_wx_set_essid fix
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.
Since an essid of "" is not mentioned in the iwconfig man page.

c580f67fd7 [PATCH] ipw2200: SIOCGIWFREQ ioctl returns frequency rather than channel
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.

d685b8c226 [PATCH] ipw2200: Enable rtap interface for RF promiscuous mode while associated
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
