Thanks for your feedback and guidance on this.
I am trying to understand the problem you mentioned during IGTK rekeying. Today I ran tests with two stations connecting an AP. MFP is enabled on all of them.
On hostapd side, my observation is add_key() is always called followed by set_default_mgmt_key(). set_default_mgmt_key() sets the key added by add_key() as default key.
We are ignoring set_default_mgmt_key() and updating Tx key index during add_key() itself.
Your concerns is we should not update Tx key index during add_key(). Reason is IGTK rekeying is not yet completed with all stations. Right?
Regards,
Amitkumar
