Zhu Yi 0a7bcf261e [PATCH] ipw2200: stack reduction 
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:

Before:

   text    data     bss     dec     hex filename
  75177    2472      44   77693   12f7d drivers/net/wireless/ipw2200.ko

After:

   text    data     bss     dec     hex filename
  61363    2488      44   63895    f997 drivers/net/wireless/ipw2200.ko

So about a ~18% reduction in module size.

	README
	------

	This directory is mostly for Wireless LAN drivers, in their
various incarnations (ISA, PCI, Pcmcia...).
	This separate directory is needed because a lot of driver work
on different bus (typically PCI + Pcmcia) and share 95% of the
code. This allow the code and the config options to be in one single
place instead of scattered all over the driver tree, which is never
100% satisfactory.

	Note : if you want more info on the topic of Wireless LANs,
you are kindly invited to have a look at the Wireless Howto :
		http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/
	Some Wireless LAN drivers, like orinoco_cs, require the use of
Wireless Tools to be configured :
		http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html

	Special notes for distribution maintainers :
	1) wvlan_cs will be discontinued soon in favor of orinoco_cs
	2) Please add Wireless Tools support in your scripts

	Have fun...
