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.
