This patch doesn't apply.
Oh, linville merged stuff on the 25th. That's the day I updated
my tree to do this patch. But seems like I did it just before
the merge.
Who could suspect that linville merges something. :D
*me runs away*

Anyway. Here's an updated patch.
NACK this version. It applied correctly, but introduced a new problem. My device occasionally gets 
deauthentication messages from my AP.Preciously, it would do a scan or two, and then reauthenticate. 
After your patch was applied, it never stops scanning.
Oh, well... It's impossible to completely fix softmac race issues.
I am _not_ going to rewrite huge parts of softmac to get locking
working. If you want this to be fixed, please hack up a solution by
yourself. I'm really not going to do more work on softmac. This
has various reasons. 1) I cannot reproduce all these bugs I'm hunting
2) Time is spent better at d80211 or other projects.

But to debug the problem:
Why do you get deauth messages? Broken AP?
I'd say that it's _correct_ behaviour to stop working
after getting a deauth ;). wpa_supplicant is responsible to re-auth.
Why doesn't it re-auth? Or does it do and it just doesn't work as
expected?
