Not sure if one size fits all. Is one minute sufficient? Can you at 
least provide module parameters that can override your defaults when the 
driver loads. It would nice to have some control over extending the 
accept times if necessary. Maybe something at listen time that could 
indicate the need to send the MRA with a backoff time?
