i40iw: Ignore LLP_DOUBT_REACHABILITY AE
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.
