Below patch was developed after discussion with Daniel Drake who
mentioned to me that wireless tools expect an EAGAIN return from getscan
so that they can wait for the scan to finish before printing out the
results.

This fixes a spinlock recursion on receiving a reassoc request.
On reassoc, the softmac calls back into the driver. This results in a
driver lock recursion. This schedules the assoc workqueue, instead
of calling it directly.
Probably, we should defer the _whole_ management frame processing
to a tasklet or workqueue, because it does several callbacks into the driver.
That is dangerous.
This fix should go into linus's tree, before 2.6.17 is released, because it
is remote exploitable (DoS by crash).

We don't make much of an attempt to fall back to lower rates, and 54M
just isn't reliable enough for many people. In fact, it's not clear we
even set it to 11M if we're trying to associate with an 802.11b AP.
This patch makes us default to 11M, which ought to work for most people.
When we actually handle dynamic rate adjustment, we can reconsider the
defaults -- but even then, probably it makes as much sense to start at
11M and adjust it upwards as it does to start at 54M and reduce it.

It currently takes something like 8 seconds to do a scan, because we
spend half a second on each channel. Reduce that time to 20ms per
channel.

After a scan, we weren't switching back to the original channel if we
were associated with an AP. So NetworkManager's periodic scans would
disrupt connectivity until the ESSID was manually set again. Fix that.

Softmac scanning fails because the stop flag is not cleared before
scanning is started. The attached one-line patch fixes this.

Recently the deauth packet handler was updated to use a deauth packet
struct (identical to the auth packet struct) and this now gives a
warning. This patch updates the code to properly use a deauth struct and
deauth variable.
