This value indicates > infinite retry and the counter is not decremented. I wonder what if the user set RNR retry larger than 7? Say the user set the RNR retry attribute to 10, is he expecting a 10-time retry or an infinite retry? In the current implementation, any larger-than-7 retry count causes infinite retry. Is this an expected behavior? Regards, Fan
