Thank you again for updating the patch set!

With this new patch #12, it worked OK for me.   I tested on my PS3 with:

  - wireless_tools version 28 and 29.  Both 64 and 32-bit compiled
    iwlist and iwconfig
  - wpa_supplicant 0.6.x, 64 and 32-bit compiled
  - gelic and zd1211 driver
  

checkpatch.pl complained some error/warnings on the patches #7, #9 and
#12.  It seemed that most of them were inherited from the original code,
some seemed like newly created ones, like 80-characters over warnings in
net/mac80211/mlme.c.  We might want to fix them?

Anyway the code works fine.  Again, thank you!
