There is just one problem with that patch (or Intersil documentation)..
Changed WEP keys should be taken into use only after port0 has been
reseted. I haven't merged this patch into the CVS for this reason since
I haven't had time to test it thorougly.

Anyway, if one is using host decryption and encryption, this port reset
should not be needed (assuming WEP was already set before). I will need
to experiment a bit more with this and make that reset code conditional
at least for station mode.

I think there is a difference in how Cisco AP and hostapd handle new .11
authentications and .1x. If I remember correctly, I decided to start new
.1x authentication only when the station arrives for the first time and
not for the possible re-authentication. But yes, I would agree that it
would be nicer if the station would not start new authentication every
time WEP setup is changed.
