You could rollback wpa_supplicant using svn/cvs but it's a bit painful 
as the changes were extensive due to the switch from the 0.5 series 
releases to 0.6.  Alternatively you could rollback your entire tree to 
r189262 (I think) and you'd have the previous code.

We do not use any of these files.  You might be better off looking at 
diff's between 0.6.8 and 0.6.9 and selectively applying changes to 
usr/src/contrib/wpa.  Some of these may be ignored as Jouni took back 
some changes I provided him.

Note that usr.sbin/wpa/wpa_supplicant has the driver for freebsd and a 
reach-over Makefile; we do not use Jouni's bsd driver or his build 
structure.

I'll try to look at merging 0.6.9 quickly.
