From db36c06cc6802d03bcba08982377f7c03a3cda7f Mon Sep 17 00:00:00 2001 From: Chris Leech Date: Tue, 3 Nov 2009 11:46:24 -0800 Subject: [SCSI] libfc, libfcoe: FDISC ELS for NPIV Add FDISC ELS handling to libfc and libfcoe, treat it the same as FLOGI where appropriate. Add checking for NPIV support in the FLOGI LS_ACC service parameters.
