+Subject: Fixup command response translation
+From: Brian King <brking@linux.vnet.ibm.com>
+References: 459383 - LTC50695
+
+If a link down event is received, outstanding commands may get
+returned to the ibmvfc driver with a "transaction cancelled implicit"
+response. This is currently translated to DID_ABORT, which does
+not get retried by SCSI core, but rather passes the failure up
+the stack. This can result in I/O errors at the filesystem level.
+Fix up this response a well as a few other error responses.
