scsi: core: Retry INQUIRY after timeout
Description from: Martin Wilck <[email protected]>:
The SCSI mid layer doesn't retry commands after DID_TIME_OUT (see
scsi_noretry_cmd()). Packet loss in the fabric can cause spurious timeouts
during SCSI device probing, causing device probing to fail. This has been
observed in FCoE uplink failover tests, for example.
This patch fixes the issue by retrying the INQUIRY.
