The LLP_DOUBT_REACHABILITY Asynchronous Event (AE) is an early warning of a connection issue. It is followed by LLP_TOO_MANY_RETRIES AE, if the retransmit threshold is reached and recovery is not possible for the connection. Currently we terminate the connection on receiving the LLP_DOUBT_REACHABILITY AE. Ignore this AE and terminate the connection only on LLP_TOO_MANY_RETRIES AE. This improves the user experience on cable disconnect/reconnect scenario while running iWARP traffic. On cable disconnect, the QP traffic is paused and the user has a larger and more reasonable timeout within which if the cable is reconnected, traffic can continue.
