Thanks for the split. I increased the scope and been looking in the 
cookie usage in the wireless subsystem. So I have a series lined up to 
change the cookie to an input parameter and have cfg80211 hand out the 
cookie value (it already has cfg80211_assign_cookie() function). This
will also cover zero cookie fix here. So I would suggest to drop this 
patch and only let the PMKID patch go in.
