Did you test IGTK rekeying? This patch looks exactly as broken as it did
the last time it was proposed more than a year ago and after the same
concern not receiving any reaction.. hostapd will configure two
different IGTKs with different Key IDs and change the TX key on the AP
once all associated STAs have the new key. If the driver does not
support updating the TX key index, either the old or the new STAs
associated after rekeying will not have the correct key.
