hostapd-0.6.8 + madwifi + bridge + WPA-PSK

Sun Feb 22 12:59:00 PST 2009

I have just been browsing the archives and found this post that  
describes exactly the same problem:

http://lists.shmoo.com/pipermail/hostap/2008-July/018021.html

Then there is an answer in the next mail in the thread and i quote:  
"You need eaaab2bd98b0b08f1ff77303a0f142af029884a6." What does this  
mean is it a revision from the cvs/svn you are using? I get the  
impression that someone fixed this, but I don't see how :D.

Regards,
Michael
