From 0558056c1ecd177f2621fc2a0484d565270f7ae1 Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 24 May 2011 11:40:48 -0400 Subject: [SCSI] lpfc 8.3.24: Miscellaneous Fixes and Corrections Miscellaneous Fixes and Corrections - Remove the memset in the lpfc_sli4_remove_rpi_hdrs call. - Correct swapping of SGE word 2 relative to offset value - Reorganize CQ and EQ usage to comply with SLI4 Specification. - Expand the driver to check the rn bit. Only detect an error if the error bit is set and the RN bit is NOT set. - If mailbox completion code is not success AND the mailbox status is success, then and only then will the driver overwrite the mailbox status. - When driver initializing device, if the device is on a PCIe bus, set PCI's "needs fundamental reset" bit so that EEH uses fundamental reset instead of hot reset for recovery. - Prevent driver from using new WWN when changed in firmware (until driver reload) - When HBA reports maximum SGE size > 0xffffffff (infinite), override with 0x80000000. - Fixed potential missed SLI4 device initialization failure conditions. - Added 100ms delay before driver action following IF_TYPE_2 function reset. - Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node. - Add a check for the CVL received flag in the fcf inuse routine to avoid unregistering the fcf if Devloss fires before Delay discover timer fires.
