ARC4 is a bit weird.  The same function is used for encryption and 
decryption, so the stream is not reset.  You will likely need to set the 
key prior to each encrypt/decrypt operation.

I'm still not fully sure we need the IV.  EAPoL Key-IV is only used in 
certain situations.  Lets try to find an AP / trace that actually sets 
the IV field.
