    [SCSI] zfcp: fix adapter (re)open recovery while link to SAN is down · f76ccaac
    Daniel Hansel authored
    FCP device remains in status ERP_FAILED when device is switched online
    or adapter recovery is triggered  while link to SAN is down.
    
    When Exchange Configuration Data command returns the FSF status
    FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE it aborts the exchange process.
    The only retries are done during the common error recovery procedure
    (i.e. max. 3 retries with 8sec sleep between) and remains in status
    ERP_FAILED with QDIO down.
    
    This commit reverts the commit 0df13847
    (zfcp: Fix adapter activation on link down).
    When FSF status FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE is received the
    adapter recovery will be finished without any retries. QDIO will be
    up now and status changes such as LINK UP will be received now.
