hostapd does not issue EAP Identify challenge

Returning to this topic, which has not reached any closure, 
investigation reveals that when hostapd is used with the wired driver, 
it responds to EAPOL and DHCP messages from the network, but never 
independently issues messages to the client network.

If the hostapd configuration is refreshed due to SIGHUP, or it is 
terminated via SIGTERM, it does not send a polite deauthentication 
message to the authenticated client when the authentication is 
cleared.  This leaves the client hanging.

Likewise, when hostapd is started, it does not send any messages to 
the client network, leaving the authenticated client hanging in a 
limbo state where it will continue to try to send packets through the 
blocked interface.  Only a client which decides to send a EAPOL or 
DHCP message will become re-authenticated and thereby unblocked.

I am still searching for the best way to solve this issue.  Any useful 
opinions are appreciated.
