From ef3eb71d8ba4fd9d48c5f9310bc9d90ca00323b4 Mon Sep 17 00:00:00 2001 From: Felix Beck Date: Fri, 16 Jul 2010 15:37:42 +0200 Subject: [SCSI] zfcp: Introduce experimental support for DIF/DIX Introduce support for DIF/DIX in zfcp: Report the capabilities for the Scsi_host, map the protection data when issuing I/O requests and handle the new error codes. Also add the fsf data_direction field to the hba trace, it is useful information for debugging in that area. This is an EXPERIMENTAL feature for now.
