From eb66dc60be5a72bc940458a5adfd400e4d810d49 Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Mon, 12 Nov 2007 10:30:58 -0800 Subject: [SCSI] qla2xxx: Correct NPIV support for recent ISPs. Firmware will export to software the maximum number of vports supported for any given firmware version and ISP type. Use this information rather than the current hardcoding of limitations within the driver.
