    [SCSI] libsas: use libata-eh-reset for sata rediscovery fis transmit failures · b52df417
    Dan Williams authored
    Since sata devices can take several seconds to recover the link on reset
    the 0.5 seconds that libsas currently waits may not be enough.  Instead
    if we are rediscovering a phy that was previously attached to a sata
    device let libata handle any resets to encourage the device to transmit
    the initial fis.
    
    Once sas_ata_hard_reset() and lldds learn how to honor 'deadline' libsas
    should stop encountering phys in an intermediate state, until then this
    will loop until the fis is transmitted or ->attached_sas_addr gets
    cleared, but in the more likely initial discovery case we keep existing
    behavior.
