From 2c3dfe3f6ad8daff5acdb01713e4f2b116e78136 Mon Sep 17 00:00:00 2001 From: Seokmann Ju Date: Thu, 5 Jul 2007 13:16:51 -0700 Subject: [SCSI] qla2xxx: add support for NPIV Following patch adds support for NPIV (N-Port ID Virtualization) to the qla2xxx. - supported within switched-fabric topologies only. - supports up to 63 virtual ports on each physical port.
