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.

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.)

I've added a new module param "bt_coexist" which defaults to OFF.

This does not seem to fix the firmware restarts, but it does do "the
right thing" and disables something that we were enabling by default:
signaling the Bluetooth h/w which channel we're on (whether or not the
BT h/w was out there).

The indirect SRAM/register 8/16-bit write routines are broken for
non-dword-aligned destination addresses.

Fortunately, these routines are, so far, not used for non-dword-aligned
destinations, but here's a patch that fixes them, anyway.

The attached patch also adds comments for all direct/indirect I/O routine

The ipw2100 driver misunderstood the parameter of txpower.
Tx Power off means turn off the radio, but the driver interpret it as
"can't set txpower". So when getting the txpower, it sets disabled=1 to
the iwconifg tool in managed mode. And the tool will display "Tx Power off"
when disabled=1.

Now, in managed mode, iwconfig will not show "TX Power" if the radio is not
switched off. It will only display "Tx Power off" only if the radio is killed.

To support IEEE 802.11h in IBSS, an ibss_dfs field is added to struct
ieee80211_network. In IBSS, if one STA sends a beacon with DFS info
(for radar detection), all the other STAs should receive and store
this DFS.  All STAs should send the DFS as one of the information
element in the beacon they are scheduled to send (if possible) in
the future.

Since the ibss_dfs has variable length, it must be allocated
dynamically. ieee80211_network_reset() is added to clear the ibss_dfs
field. ieee80211_network_free() is also updated to free the ibss_dfs
field if it is not NULL.
