I was a bit unclear when saying it does not support rekeying. Yes,
these are new individual WEP keys and that key is indeed changed on
reauthentication. The rekeying functionality that was added after
2002-10-12 release is rekeying both broadcast and unicast keys without
reauthentication (i.e., it can be done more often without needed to talk
to RADIUS server).
