From dcf2a4e0792e837d6133506444a033a95cbc9616 Mon Sep 17 00:00:00 2001 From: James Smart Date: Wed, 29 Sep 2010 11:18:53 -0400 Subject: [PATCH] [SCSI] lpfc 8.3.17: SLI Additions and Fixes - Added driver support for management application to pass down two security specific mailbox commands (MBX_SECURITY_MGMT and MBX_AUTH_PORT) - Added driver support for handling FIPS zeroization trap of host ERATT ER8, performing selective reset and bringing the device up. - Added code to detect INIT_LINK mailbox command completion returning status MBXERR_SEC_NO_PERMISSION. - Increased the wait timeout on host status register HS_FFRDY and HS_MBRDY being set. - Remove the port offline code from the Heartbeat TMO handler.
