This should speed up station lookup when "should speed up"? Do you have numbers to back that up? Read this as - you need to do more to convince me that the double accounting and software complexity is worth it. And then, if we really want/need to have the double accounting and all the associated complexity and potential problems, perhaps making per- interface lists, perhaps even replacing the global list (since we still have a global hash table), or something similar would make more sense? johannes
