From 2ccdf0dce41a39db3721fe801dac5c5effa8e4be Mon Sep 17 00:00:00 2001 From: Vikas Chaudhary Date: Fri, 30 Jul 2010 14:27:45 +0530 Subject: [SCSI] qla4xxx: updated mbx_sys_info struct to sync with FW 4.6.x Also, changed boundary checking from size of total structure to verification that we received the amount of data needed to cache inernally. This change will provide compatibility with mbx_sys_info structure sizes in both older and newer firmware versions.
